General/Location:

Before you set up the microscope, you must choose a suitable location. Firstly, you must make sure that your micro-scope is on a stable and solid surface. For observations with the electric illumination, an electrical power outlet is required.

Eyepiece

For observation with this microscope, two eyepieces (1) are required. With the eyepiece and with a chosen objective lens, you can choose the magnification of the microscope. The eyepiece is inserted into the head from above.
TIP:
Begin each observation with the lowest magnification. So, the centering and focus-sing of the object to be viewed is easy.

Built in electric illumination

The microscope has a built-in electric illuminator. It works by plugging the connection cable into the microscope and the electricity supply. It can be switched on or off with the switch (14) of the microscope.
Use the dimmer (15) to change the intensity of the light.
The condenser (10) is part of the lighting. Adjust it using the height adjustment (11) so that you get a well-illuminated image. Most observations require the condenser to be in the highest position. The condenser diaphragm (10a) is used to adjust the illumination according to the aperture of the objectives. Correct diaphragm setting ensures optimum resolution. At higher magnifications, the diaphragm must be opened further (turn lever to the left). A (too wide) closed condenser diaphragm will increase contrast and depth of field, but fine details will be lost.

Adjust the interocular distance

The interocular distance varies from person to person. In order to achieve a perfect interaction between your eyes and the eyepieces, the eyepiece distance should be adjusted before the first observation. Look through the eyepieces and adjust the interocular distance control (3) until you reach a single, round image. Keep the value on the scale in mind for a faster adjustment the next time.

Observation

• You begin each observation with the lowest magnification (eyepiece 10x and objective 4x). So that the object to be viewed is centred and properly focussed.
• The higher the magnification the more light is required for good picture quality.
• The use of the 100x objective is intended exclusively for examinations with oil immersion.

Begin with a simple observation.
Turn the nosepiece (6) onto the smallest magnification and insert the 10x eyepieces. Now, place a prepared slide under the objective on the microscope table (7). Move the preparation on the table with the two adjusting screws (8 and 9). Now, look through the eyepieces (1) and turn the coarse adjustment (12) carefully until the image becomes visible. The definition is applied by the fine adjustment (13). Make sure that you never overtighten the fine adjustment. If you don’t reach a sharp image after the fine adjustment, you may adjust the diopter setting (4) until it matches your eye. For this, turn the diopter setting (4) to O, look through the eyepieces and close your left eye. Focus the object for your right eye using the coarse and fine focussing wheels (12 and 13). Now, close your right eye and look only with the left eye through the left eyepiece. If the image isn´t sharp, turn the diopter setting (4) to get a sharp image.

The microscope table

With the microscope table (7), you can look at your preparation in a precise position and to the exact millimeter. The object is placed between the clamps on the microscope table. Move the object, with help of the axis adjustments (8 and 9), directly under the objective. With the built-in vernier at both axes you can now specifically set and shift the object. Your sample can now be viewed with different magnifications.

Oil immersion

Directions for observation with oil immersion. Put a drop of immersion oil (16) onto the upper lens of condenser and raise the condenser by using the height adjustment (11) until the oil touches the slide from below. Centre your object, with middle magnification, and with the light illumination on. Move the nosepiece with the coarse focusing wheel up high and screw in the 100x objective. Take a drop of immersion oil and place it on the preparation. Move the objective down carefully with the coarse adjustment, until it touches the immersion oil. Look through the eyepiece and focus with the fine adjustment. Do not forget to clean the objective, the preparation, and the condenser after the observation with some alcohol.

Changing the fuse

(Fig. 2)

A fuse is built in for safety reasons. Should it burn through, replace it as below: Pull the plug and lay the instrument carefully on its side. Carefully, undo the ”FUSE” screw (1). Use a small screwdriver for the purpose and press the screw a little in to undo it. Remove the old fuse and insert a new one of the same type. Retighten screw and fuse again. The microscope is now ready for use again.

Only for Trino (Art.No. 57-23100):

Photography using the Researcher Trino
The trinocular head on the Researcher makes it possible to take pictures using a mirror reflex camera or a Bresser MicrOcular.
NOTE!
The Researcher Trino was designed for use with a Bresser MicrOcular. When using a SLR camera the large picture area causes shad-owing. This worsens the greater the enlargement.

Using the Bresser MicrOcular:
The Bresser MicrOcular can be inserted in the extension tube (A) of the trinocular head.
The head is so designed that the MicrOcular and the eye-pieces can yield a homofocal image. To do so first focus on the object in the eyepieces. Then look at the camera’s live view. Undo the counter-ring (B) on the extension tube. Turn the extension tube to adjust camera eyepiece focus. Retighten it once focussed. For optimal focussing use the 10x or 40x objective. Employ a photo adaptor and a cam-era-specific T2 ring when using a mirror reflex camera. Ater attaching the adaptor to the camera, the combination is inserted in the extension tube (A).
You may not be able to focus correctly as the microscope table cannot be raised sufficiently. Undo the table up stop (18) and raise the table appropriately. When changing objectives lower this table a little to prevent the objective touching the specimen.

NOTES on cleaning

1. Avoid disassembling the microscope!
   Because of being a precise optical instrument, do not disassemble the microscope. That may cause serious damage to its performance. Do not disassemble the objectives.

2. Avoid contamination!
   You should make sure that dust or moisture do not come in contact with your microscope. Avoid putting fingerprints on any optical surfaces! If dust or dirt nevertheless have gotten onto your microscope, or the accessories, remove it as described below.

3. Cleaning non-optical parts:
   Disconnect the plug from mains socket before cleaning non-optical parts of the microscope (e. g. the frame or the stage). Firstly, remove dust or dirt from your micro-scope, or accessories, using a soft brush. Then clean the soiled area with a soft, lint-free cloth; the cloth may be moistened with a mild detergent solution. Be sure that the microscope is dry before using. For cleaning the painted parts or plastic components, do NOT use organic solvents such as alcohol, ether, acetone, xylene or another thinner etc.!

4. Cleaning optical parts:
   In order to enhance the optical quality, the lenses of eye-pieces or objectives are coated. They should not be wiped because dry dirt or dust may scratch the coating. It is best to remove the parts to be cleaned from the frame prior to cleaning. Always blow loose dust away first. Use lens tissue of good quality or soft fabric moistened with a small amount of pure alcohol (available in the chemist’s shop); wipe the lens surface clean.

5. Cleaning the oil immersion lens:
   After working with oil immersion, the immersion oil should be removed from the lens of the 100x objective at the end of each workday. In order to do this, use a lens tissue moistened with a small amount of pure alcohol (available in the chemist’s shop). Don’t forget to clean the preparation, too.

6. When not in use:
   After usage, cover the microscope with the dust cap (made of plastic) and place it where it is dry and mouldless. In the case of non-use for a longer time, you should stow the microscope and the accessories in their correct containers again. We suggest the storage of all objectives and eyepieces in a closed container with drying agent.

Remember: A well maintained microscope will keep its optical quality for years and thus maintain its value.
