Product Usage Instructions

Initial Setup

Connect the camera to the video adapter using a C mount.
Attach the LED to the light block.
Align the optical block with the base plate.
Attach the turret/dust plug to the optical block.
Select the appropriate LWD objective lens based on desired magnification.
Attach the selected objective lens to the quad nosepiece.
Adjust the Z-axis bracket to align the fiber optic connectors for viewing.

Operation

Focusing:
Use the focus slide, focus micrometer, and focus knob to adjust the focus of the image.
Clockwise = Focuses the Stage In Counter-clockwise = Focuses the Stage Out
Lighting
The illumination can be controlled using the “On/Off LED Intensity” control knob located on the ME-12013 power adapter/LED controller. This allows the operator to control the brightness of the image when inspecting the dark fiber cladding and highly reflective metal or ceramic ferrules.
Clockwise = Increases Illumination
Counter-Clockwise = Decreases Illumination

Changing magnifications:
The DE2503 model is equipped with three objective lenses: 5x, 10x, and 20x. Mounted to a typical microscope turret or nosepiece allowsthe operator to quickly change magnifications when inspecting connectors. Optional 3.3x and 40x objectives are also available. ****
DE2503 stage adjustments:
Centering on the DE2503 can be accomplished along 2 axis. The lever in the front of the stage acts as a lock, flipping the lever to the right hand side of the scope unlocks the stage while flipping
it to the left locks the stage.
Quickly change adapter positions by unlocking the stage and sliding the stage left or right. After locking the stage, use the knob on the right to accurately move the stage along the x-axis up to 0.5 inch. Each adapter has its own individual z-axis adjustment.
Changing adapters on the DE2503:
Adapters on the DE2503 stage can quickly be changed out by loosening the two screws. When aligning the adapters use the lower powered 5x objective.
Individual adapters can be moved back and forth to align them with others. This is used to “parfocal” the adapters to one another. Being parfocal minimizes the amount of focusing required when switching connector styles.
****
Setting APC adapters on the DE2503:
Use the two end positions on the DE2503 stage for setting up 2.5mm or 1.25mm adapters. A third mounting hole is provided to angle the adapter at 8°. Insert the connector key up on the left hand position and key down on the right hand position.
As with setting up any bracket it may be easier to use the low (5x) powered objective first. The angle can then be checked by inserting a connector and making sure the light is centered.

Preventive Maintenance

Regularly clean the lenses and optical block with a soft, lint-free cloth. Avoid touching the lenses with bare hands as oils from skin can damage the lenses. Store the microscope in a dry, dust-free environment.
Caution:
The following instructions should only be performed by qualified service personnel.
Warning:

If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
There is NO SERVICEABLE EQUIPMENT inside the
ME-12013 LED controller. All equipment requiring repair should be sent back to the manufacturer or an authorized dealer.

Note: The DE2503 microscope is relatively low in maintenance. Basic care and precaution in using the instrument is required. Depending on cleanliness of the general working area as well as the age of the equipment, we would suggest at least semi-annual service and maintenance.

General cleaning

Harsh solvents are not recommended on a regular basis. Typical safe de-greaser solvents can be used to clean old grease or grime from mechanical parts. Lens cleaner offered at most photo/camera supply stores is safe to use on the optics of our microscopes. Lens cleaner can be used with a soft lens tissue/cloth to remove any soil, fingerprints, etc. from the front of the objectives.
Centering the illumination
Centering the illumination of the DE2503 is critical in order to maximize performance of the microscope. All scopes are set up from the factory, but replacing lamps or periodic cleaning of the beam splitter may require the operator to re-center the illumination.

Using a 3/32” hex wrench, loosen the four socket head screws surrounding the light block.
While viewing a fiber on the monitor, slide the light block around until the greatest amount of light is over the cladding area of the fiber.
Re-tighten the four screws.

Cleaning objective lenses
Oils, dirt, and fingerprints may reduce the resolving power of the objective lenses. To ensure maximum levels of performance of the DE2503, wipe the lens of the objectives with a lint-free tissue and lens cleaner. Ordinary lens cleaner, available at most photography supply stores works the best. Perform this procedure weekly or as needed, depending on the type of environment inspection is being held.
Cleaning the prism
Primarily an issue with older models, where frequent changes of the tungsten lamp caused debris to fall onto the prism. If for some reason the illumination or resolution diminishes and cleaning the objectives had no effect, cleaning the prism may be accomplished in just a few simple steps.

Using a 3/32” hex wrench, remove the four socket head screws surrounding the light block.
Lift the light block off of the microscope exposing the prism or beam splitter.
Without removing the prism, use clean compressed air to blow any debris off of the top of the prism.
If there is still visible dirt and debris, use lens cleaner and lint-free lens cloth to clean the prism. Use caution not to leave any streaks.
Replace the light block and follow the procedures for centering the illumination as described on page 9.

Cleaning the camera
Use extreme caution when attempting to clean the camera. Any scratches, solvent, streaks or dirt left on the IR filter of the camera will show up in the field of view of the microscopes.
Before attempting to clean the IR filter on the camera, first confirm that the visible dirt on the monitor is actually on the camera. While viewing the suspected dirt on the video monitor, slowly rotate the camera on the Microscope.
Due to the orientation of the camera, if the dirt remains in the same spot and does not rotate with the camera, then it most likely is on the camera itself.

Carefully unscrew the camera from the camera mount.
Using clean, compressed air, blow across the surface of the IR filter.
Re-check the camera for dirt.
If the dirt is still there, use plastic tweezers, soft lens cloth and lens cleaner to carefully wipe the surface of the IR filter. Use a wiping spiral pattern from center of filter out to edges to remove debris.
Re-check the camera for dirt.
Repeat this process until the camera is clean.

As a last resort, carefully try to wipe stubborn dirt from the IR filter in the front of the camera. Use Lens Cleaner and Lens Cloth obtainable from any retail camera store.

DE2503 stage maintenance

Periodically clean and lubricate the slide on the DE2503 to ensure reliable and accurate position of the test connectors.

Using a small Philips head screw driver, unscrew the two button head screws on the right side of the slide.
Carefully slide the top of the stage assembly away from and off of the dovetail base.
Clean the dovetail and the slider using any common de-greaser.
Be sure to remove any debris such as connector caps that may have fallen into the slide.
Using a medium grease, lightly spread the grease over the dovetail and pads of the slider.
Re-fit the top half of the slide back on to its dovetail base and run it back and forth to further distribute the grease.
Replace the end of the slide.

Lubricating the focus micrometer
Occasional lubrication of the focus micrometer will ensure accurate and repeatable results.

Unscrew the focus knob and carefully remove the micrometer drum.
Clean the micrometer drum with de-greaser.
Lubricate the drum and threads with a light grease.
Carefully replace the micrometer drum by screwing it back into the housing.

Determining actual magnification
The best method to calculate the exact “total” magnification used on the DE2503 is to measure the cladding on the video display. Take the measurement in millimeters and divide that amount by the 125 micron cladding. The result is the “total” optical and video magnification being used.
For example: taking a set of calipers, we measured the diameter of the ferrule viewed through DE2503 on a monitor to be approximately 53.49mm. Actual size on display/cladding diameter in mm = total magnification 53.49mm / .125mm = 427.92X DOMAILLE ENGINEERING DE2503 Fiber Optic Inspection Scope
