Features
• High Resolution video and camera.
• Quadruple Turret Nosepiece Long Working Distance Optics for
UPC, APC, and Multi-Fiber inspection.
• An extensive range of adapters for most connectors.
• Custom adapters available upon request.
Initial Setup
After unpacking the DE2503 microscope
and accessories, set up can be quickly
achieved through a few simple
connections. There are three main
components to the microscope
system, the microscope, power
adapter/LED Controller, and
monitor (or computer using
a frame grabber).
The ME-12013 LED Controller operates from a 24 volt DC output
power adapter (ME-12015) with switching transformer to accept
AC voltage 90-240 volt, 50-60Hz for domestic or international use.
This unit is used to power both the camera and the illumination of
the microscope.
Currently we provide two different monitor types, in several different
sizes. These monitors are high resolution monitors specifically
chosen to provide the best solution for inspecting connector
end-faces. We do not recommend any of the lower priced security
type monitors as the resolution and image quality are not sufficient.
A computer may also be used to capture images, contact Domaille
Engineering for more information on digital camera options or video
frame grabbers.

Operation
Focusing
The Focus Adjustment Knob is conveniently
located next to the stage. Turning the
knob adjusts the contrast of the image
with precision and control.
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.
5
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.
6
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
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.
8
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.
1. Using a 3/32” hex wrench, loosen the four socket head screws
surrounding the light block.
2. 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.
3. Re-tighten the four screws.
Incorrect Illumination:
Notice how the light is
towards the bottom of
the screen.
Correct Illumination:
Notice how the light
surrounds the cladding.
Light scratches can now
be easily detected.
9
Cleaning objective lenses
Oils, dirt, and finger prints 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.
1. Using a 3/32” hex wrench, remove the four socket head screws
surrounding the light block.
2. Lift the light block off of the microscope exposing the prism or
beam splitter.
3. Without removing the prism, use clean compressed air to blow
any debris off of the top of the prism.
4. 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.
5. Replace the light block and follow the procedures for centering the
illumination as described on page 9.
10
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.
1. Carefully unscrew the camera from the camera mount.
2. Using clean, compressed air, blow across the surface of the
IR filter.
3. Recheck the camera for dirt.
4. 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.
5. Re-check the camera for dirt.
6. Repeat this process until the camera is clean.
11
Blow air across and not directly at the
CCD chip of the camera.
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.
12
DE2503 stage maintenance
Periodically clean and lubricate the slide on the DE2503 to ensure
reliable and accurate position of the test connectors.
1. Using a small Philips head screw driver, unscrew the two button
head screws on the right side of the slide.
2. Carefully slide the top of the stage assembly away from and off of
the dovetail base.
3. 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.
13
4. Using a medium grease, lightly spread the grease over the
dovetail and pads of the slider.
5. 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.
6. Replace the end of the slide.
14
Lubricating the focus micrometer
Occasional lubrication of the focus micrometer will ensure accurate
and repeatable results.
1. Unscrew the focus knob and carefully remove the
micrometer drum.
2. Clean the micrometer drum with de-greaser.
3. Lubricate the drum and threads with a light grease.
4. 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
