General safety instructions
Intended use: a non-medical device
This microscope is intended for general observation of cells and tissues, with
transmitted/reflected illumination and with the specimen fixed on a slide
Intended use: medical device class l
This microscope is intended for observation and diagnostics of cells and
tissues at hospitals or by physicians and veterinaries in private practice in
pathology, anatomy and cytology applications. To be used with transmitted/
reflected illumination and with the specimen fixed on a slide. Physicians and
veterinaries use microscopes to identify the different types of cells and spot
abnormal cells. This product helps in identifying and treating diseases
Dangers associated with the operation
- Improper use could result in injury, malfunction or damage to property. It must be ensured that the operator informs every user of existing hazards
- Danger of electrocution. Disconnect the power to the entire lighting system before installing, adding or changing any component
- Not to be used in corrosive or explosive environments
- Avoid direct exposure of eyes to the collimated light beam or direct light from the light guides or fibers
- To avoid a hazard to children, account for all parts and keep all packing materials in a safe place
Photobiological safety LED, important safety instructions
- Avoid direct eye exposure to any LED light source while switched on
- Before looking through the eyepieces of the microscope, lower the intensity of the LED illumination
- Avoid long and high-intensity exposure to LED light because this may cause acute damage to the retina of the eye
Prevention of biological and infectious hazards
Infectious, bacterial or viral biohazard substances under observation may be a
risk to the health of humans and other living organisms. Special precautions
should be taken during in vitro medical procedures :
- Biological hazards: keep a logbook of all the biological substances or pathogenic microorganisms that were under observation with the microscope and show it to everybody before they use the microscope or before they do some maintenance work on the microscope! Agents can be bacterial, spores, enveloped or non enveloped virus parties, fungi, or protozoa
- Contamination hazard:
- A sample that is properly endorsed with a cover glass never comes in direct contact with the microscope parts. In that case prevention of contamination lies in the handling of the slides; as long as the slides are decontaminated before use and are undamaged and treated normally, there is virtually zero risk of contamination
- A sample that is mounted on a slide without cover glass, can come in contact with components of the microscope and may be a hazard to humans and/or the environment. Therefore, check the microscope and accessories for possible contaminations. Clean the microscope surfaces and their components as thoroughly as possible. Should you identify possible contamination, inform the local responsible person in your organization
- Microscope operators could be contaminated by other activities and cross-contaminate components of the microscope. Therefore, check the microscope and accessories for possible contaminations. Clean the microscope surfaces and their components as thoroughly as possible. Should you identify possible contamination, inform the local responsible person in your organization. it is recommended to wear sterile gloves when preparing the slides and handling the microscope in order to reduce contamination by the operator
- Infection hazard: direct contact with the focusing knobs, stage adjustments, stage, and eyepieces/tubes of the microscope can be a potential source of bacterial and/or viral infections. The risk can be limited by using personal eyeshades or eyepieces. You can also use personal protections such as operation gloves and/or safety goggles, which should be changed frequently to minimize the risk
- Disinfectant hazards: before cleaning or disinfecting, check if the room is adequately ventilated. If not, wear respiratory protective gear. Exposure to chemicals and aerosols can harm the human eyes, skin, and respiratory system. Do not inhale vapors. During disinfection, do not eat, drink or smoke. Used disinfectants must be disposed of according to local or national regulations for health and safety
Disinfection and decontamination:
- Exterior casing and mechanical surfaces must be wiped with a dean cloth, dampened with a disinfectant
- Soft plastic parts and rubber surfaces can be deaned by gently wiping a clean doth, and dampened with a disinfectant. Discoloration can occur if alcohol is used
- The front lens of eyepieces and objectives are sensitive to chemicals. We recommend not to use aggressive disinfectants but to use lens paper or soft fiber-free tissue, damped in a deaning solution. Cotton swabs may also be used. We recommend you use personal eyepieces without eyeshades in order to minimize risk
- Never immerse or dip the eyepiece or objective into a disinfectant liquid! This will damage the component
- Never use abrasive compounds or dealers that may damage and scratch optical coatings
- Properly clean and disinfect all possible contaminated surfaces of the microscope or contaminated accessories before storing for future use. Disinfection procedures must be effective and appropriate
- Leave the disinfectant on the surface for the required exposure time, as specified by the manufacturer. If the disinfectant evaporates before the full exposure time, reapply the disinfectant on the surface
- For disinfection against bacteria, use a 70% .aqueous solution of isopropanol (isopropyl alcohol) and apply for at least 30 seconds. Against viruses, we recommend referring to specific alcohol or non-alcohol based disinfection products for laboratories
Before returning a microscope for repair or maintenance through a Euromex dealer, an RMA (return authorization form) together with a decontamination statement must be filled in! This document – available from Euromex for any reseller- must be shipped together with the microscope at all times

Assembling Delphi-X Observer
This chapter describes the steps that need to be taken to assemble the
Delphi-X Observer microscope. Euromex Microscopes will always try to keep the
number of assembly steps for their customers as low as possible but there are
some steps that need to be taken. The steps mentioned on the following pages
are not always necessary but described for your convenience nonetheless:
The diagram shows the order of each component’s installation
Step l | Attaching the focus cassette | Step 5 | Placing the eyepieces |
---|---|---|---|

Step 1/Attaching the focus cassette
- Attach the focus cassette according to the path shown in figure 1
- The dovetail slot needs to be aligned with the slot of focusing cassette
- Slide it down until it reaches the locking pin
- Then use the hex wrench tool to tighten the screw shown as (in figure 2)
Step 2]Attaching the mechanical X/Y stage
- Tum the coarse focus knob until the elevating section is brought to the lowest position
- Attach the mechanical object stage according to fgure 3 by aligning the stage above the ring of the focus cassette
- Fix the mechanical stage into place with a screw (figure 4)
3 Step ]Attaching Nosepiece (figure 5)
- Slide the nose piece into the slot
- Fix into place with screw (II)
Step 4[Placing the microscope head (figure 6)
- Place the head by loosening the screw (Ill)
- Mount the head in its position inside the microscope arm
- Secure it by tightening the screw again
Step S[Placing the C-mount or photo port, onto the microscope head (figure7)
- loosen the screw (IV)
- Place either the C-mount or photo port and tighten the screw
Step 6[Placing and mounting the eyepieces (figure 8)
- First, remove the dustcover of the eyepiece tubes
- Insert the eyepieces into the eyepiece tubes
Step 7[Placing the condenser (figure 9)
- Use the condenser height control knob (V) to lower the condenser holder to the lowest position
- Insert the condenser into the holder as shown unfigured
- Then secure the condenser by fixing the screw indicated
- Centering the condenser is described later in this manual
Step 8]Attaching the LED Lamp HOUSING UNIT (figure 10A)
- Slide the lamp unit (Halogen or LED) into position at the back of microscope base
- Use the wrench screw tool to secure the bolt (VI)
Step ll I Connecting the power cord
The Delphi-X Observer microscopes support a wide range of operating voltages:
100 to 240 V. Please use a grounded power connection
- Make sure the power switch is off before connecting.
- Insert the connector of the power cord into the Delphi-X Observer power socket (figure 108), and make sure it connects well
- Insert the other connector into the mains socket, and make sure it connects well
- Put the power switch to ON
Do not bend or twist the power cord, it will get damaged. Use the special cord supplied by Euromex. If it is lost or damaged, choose one with the same specifications
Operation
Placing the slide
(figure 11)
- Lower the condenser slightly from the uppermost position by turning the condenser focus knob
- Open both aperture and field diaphragm entirely
- Bring the 4x objective (or lowest objective in your configuration) into the optical path by rotating the nosepiece until the right objective dicks into position
- Pull back the spring damp of the specimen holder and gently place the slide into position
- Gently release pressure from the spring clamp so it softly moves back in position securing the slide
- Use the X and Y axis control knobs of the mechanical stage to move to area of interest of the slide into the light path
Adjusting the tension of X and Y axis control knobs
(figure 12
- The degree of tension on the X and Y-axis control knobs can be adjusted
- To do that, drawdown handwheel (A) and find two adjusting rings (B, C)
- By rotating these rings the movement of the knobs can be set lighter and heavier
- Ring B is used for adjusting the X direction
- Ring Cis is used for adjusting the Y direction
Switching between light sources
(figure 13)
Next to the intensity controller, there is a button for switching between transmitted and reflected illumination. The standard brightfield configuration used for this manual does not have this option
- When the button is pushed in, the light is set to reflected mode
- When the button is pushed out, the light is set to transmitted mode (standard)
Getting the specimen in focus
(figure 14)
- Use the coarse control knobs to adjust the focus quickly and roughly
- Get the specimen into sight through the eyepieces
- Then use the fine focus control knob to adjust the focus in detail
Adjusting the coarse focus tension
(figure 15)
Next to the right side coarse focus know there is a ring for adjusting the
coarse focus tensions This can be used to make the coarse control move lighter
or heavier, according to user preference
Setting the focus lock
(figure 16
Next to the left side coarse focus know there is a ring setting the focus
lock. The focus lock can be used to limit the maximum position of the stage at
a certain height. This is ideal for preventing objectives to get damaged,
slides from breaking, or setting the stage at a reference height
- Move the stage to the desired height then fx the ring tight to lock the mechanical stage’s maximum height
- The stage still can be lowered but the highest position is now limited to the set position
- Release the ring to undo the focus lock
Switching the fine focus knobs
(figure 17 and 18
The fine focus knobs can be switched from left to right to meet user
preference
- Pull the knobs with moderate force to release the magnet which is holding the knobs onto the stand
- Attach the magnets onto the holder and let it grab the knobs again to mount them onto the holder
Adjust interpupillary distance
The Delphi-X Observer has an interpupillary distance range of 47 to 78 mm. The
correct interpupillary distance is reached when one round image is seen in the
field of view
This distance can be set by
either pulling the tubes towards each other or pulling them from each other.
This distance is different for each observer and this should be set
individually. When more users are working with the microscope it is
recommended to remember your interpupillary distance for a quick setup during
new microscopy sessions
Adjust the diopter of the eyepieces
(figure 19
In order to compensate for human eye differences, distortion, and thickness
differences in cover glasses and tune for the best parfocality between
objectives, one can use the diopter to do so. Take a well-prepared slide for
your reference:
-
Set (both) the diopter adjustments of the eyepieces to 0
-
Select the 10x objective, look for an interesting area on the specimen and focus on this area
-
Select the 40x objective and focus on the specimen
Warning: don’t change the coarse and fine adjustment anymore -
With your dominant eye open (lose your other eye), rotate the diopter adjustment from +” to” until the selected area get as sharp as possible
-
If during this operation the image becomes unsharp, take your eyes from the eyepieces and turn the diopter adjustment, without looking into the eyepieces, a few divisions back from-” to +
-
Look into the eyepiece again and turn the diopter adjustment from ‘+’to ‘ until the selected area on your specimen gets the optimal sharpness
-
Repeat for your non-dominant eye, and with the second diopter
Verification:
- Take your eyes from the eyepieces and look for 2 seconds to a far point in the room in order to reset ” your eyes
- Look again into the eyepieces.If the adjustment is not good, repeat the operation till you reach the same sharpness for the 10x and 40x objective without touching the coarse and micrometric adjustments
The correct eyepoint
(figure 20)
The eyepoint is the distance from the eyepiece to the user’s pupil. To obtain
the correct eyepoint, move the eyes towards the eyepieces until a sharp image
is reached at a full field of view
Select eyepiece and camera light throughput
(figure 21
The Delphi-X Observer gives users the option to select out of three output
types, giving large flexibility when using cameras. The push/pull rod on the
side of the microscope head can be set in 3 positions:
POSITION 1]The optical light path is sent to the eyepieces only. Ideal
for when no camera is used
POSTI0N 2]The optical light path is sent to the eyepieces for 209% only.
The ideal standard setting for when a camera is used
POSTI0N 3]The optical light path is sent to the camera only. Ideal for
when the camera is used at low light imaging
These positions are indicated on the head as well for user convenience
Icon | Action | Eyepiece/ camera |
---|---|---|
Pushrod in completely | 100/0 | |
Pull rod towards the middle | 20/80 | |
Pull rod out completely | 0/100 |
Centering the condenser
(figure 22)
- Move the condenser to the top position (1)
- Focus on a specimen using the smallest objective (f.e. 4x or 10x objective)
- Close the field diaphragm (2)
- Use screws (figure 23) to move the field diaphragm to view center
- Open the field diaphragm carefully to the outside of the field of view to ensure the field diaphragm is in the center and so the condenser has been centered properly
The aperture diaphragm (figure 24/3) should be used to adjust the numerical
aperture, not to adjust image brightness. When the aperture diaphragm is
opened to the 70 80% of the objective aperture the ideal position is reached
The simplest way to do this is to use the markings on the condenser
For example: when a 40x objective with N.A.0.65 is used, one can set the
condenser to 70 80% 0f0.65 which is 0.45to 0.58
Using LED WITH frosted filter
(figure 25)
For LED models there is only 1 push button
- Push the button in for placing the frosted filter into the light path
LED version with frosted filter
Using HALOGEN WITH LBD, ND 6, and ND25 filters
(figure 26)
The halogen version has three filter options:
- L8Dis a filter for increasing color temperature
- ND2Sis a filter with 25% light transmittance
- ND6 is a filter with 69% light transmittance
Halogen version with LBD and two ND filt ers
iCare sensor
(figure 27)
The unique iCare Sensor is developed to avoid unnecessary loss of energy. The
illumination of the microscope automatically switches off shortly after the
user steps away from his or her position
- Pushing the iCare button will re-active the light
- The iCare function is turned on by default
- To turn off the iCare function push the iCare button for4 a seconds
- The function will be deactivated and the bright LED will dim to indicate the the function has to be turned off
- Repeating this step will turn the function back on
Replacing the fuse
(figure 28)
The fuse is placed in a drawer
- To open it push the drawer aside with a screwdriver
- Take out the drawer and replace the fuse gently
Cleaning optics
Howtokeepthe optics clean?
Dust and dirt particles have a negative effect on image quality. Keeping the
optical system of your microscope lean is essential for the best image quality
and overall lifetime of your microscope. Dust and dirt on optical elements
such as lenses, prisms, and filters that are left unattended can become
difficult -or even impossible to remove and may cause mold
FIGURE A
- Place your objective or eyepiece on a secure location
- Objectives can be screwed into the cover of an objective case
- Eyepieces can be placed in the microscope box
- Condensers and collector lenses can remain in place in the microscope
FIGURE B
- To prevent scratches on coatings and optical glass try to remove dirt and dust that sticks to the optical surface first with an air-blower or with pressurized dry air (oil-free and under moderate pressure version only)
FIGURE C
- Use an absorbent lens paper or cotton swab.
- Dampen a swap or towel with a small amount of lens cleaning fluid or cleaning mixture (either pure isopropanol or a mixture of 7 parts ether and 3 parts alcohol)
FIGURED
- (lean the lens by using the tip of the cotton swap or the lens paper. Use enough lens paper so that solvents do not dissolve oils from your hands which can make their way through the paper onto the coated surface
- When deaning a large lens surface, wipe with little pressure from the center towards the periphery in a circular motion. Do not use a zig-zag motion
- Discard each lens paper or cotton swap after a single-use
FIGURE E
- Wait until the cleaning fluid is evaporated, or speed up this process by using pressurized dry air
- Check if the surface is dean by using a magnifying glass
- Place the cleaned item back on the microscope
Please note that cleaning of the optical surfaces indicated in this instruction only applies to external surfaces of objectives, eyepieces, filters, and condensers. Internal surfaces must always be done by your Euromex microscopes distributor
