Initial Setup:
Due to the delicate nature of the optics housed within the DE3200 and DE3200-S2, the microscope must
be shipped in a partly un-assembled state to ensure safe delivery.
1. Unwrap the modular focus base and vertical illuminator.
2. Remove the dust cover from the back of the vertical illuminator and the front of the focus base.
3. Using a 3mm wrench, mount the dovetail of the vertical illuminator to the modular focus base.
DO NOT overtighten the screw as it could crack or damage the mount.
Make sure that the vertical illuminator is mounted vertically on the focus base. You can check this by
looking at the space between the illuminator and the focus base for clearance.
Note: Failure to make sure the vertical illuminator is attached correctly to the focus base may lead to
serious resolution problems with the microscope.

Attaching the Micrometer (DE3200-S2)
The micrometer is packaged separately to prevent damage during shipping. To reduce wear on the
battery, it has been inserted backwards for shipping.
1. On the back on the micrometer remove the battery plate. Flip battery and replace battery
plate.
2. Remove the nut from the micrometer.
3. Insert the micrometer into the first holder, but not through the second.
4. Place the nut back onto the micrometer.
5. Read the micrometer instruction manual prior to use.
Once the vertical illuminator and micrometer have been installed, the remaining 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 if using a digital
camera or 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.
The micrometer nut

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 and Focus Tension Adjustments
The focus adjustment knob on the DE3200 series is
conveniently located on each side of the Modular
Focus Base. Both coarse and a fine adjustment are
provided. A tension adjustment is also located on
the right side of the scope.
Clockwise = Focuses the Stage In
Counter-Clockwise = Focuses the Stage Out
Lighting:
The illumination can be controlled using the intensity control knob located on the fiber optic light
source. 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:
Each DE3200 and DE3200-S2 model is equipped with four
objective lenses: 5x, 10x, 20x, and 40x. Mounted to a typical
microscope turret or nosepiece allows the operator to quickly
change magnifications when inspecting connectors. Optional
3.3x, 10x interferometer, 20x interferometer objectives, and
fiber pointer are available. The fiber pointer helps align bare
fiber quickly.

visit our website at www.domailleengineering.com
Illumination Set up:
For maximum contrast, alignment of the field diaphragm is critical in maximizing performance of the
DE3200 Series. Once set, no further adjustment should be necessary.
1. Set up an image with the fiber in the center of the monitor screen.
2. Set the magnification using the 40x objective.
3. Close the field diaphragm by sliding the knob to the left.
4. This will close the diaphragm and appear as a hexagon silhouette.
5. Use the centering knobs on each side of the Vertical Illuminator to move the silhouette of the
diaphragm so that it is centered around the image of the fiber.
Determining Actual Magnification:
The best method to calculate the exact “total” magnification used on the DE3200 series 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 DE3200
on a monitor to be approximately 53.49mm.
Actual size of display/cladding diameter in mm = Total Magnification.
53.49mm/ .125mm = 427.92x

For more information on Total Magnification or differences between optical and video magnification
please refer to the Optical versus Video section on our website www.domailleengineering.com
Linear Stage Adjustments:
Centering on the DE3200 Series can be accomplished along three axes.
The lever in the front of the stage acts as a lock, flipping the lever to the right hand side of the
scope “un-locks” the stage while flipping it to the left “locks” the stage. Quickly change positions
by “un-locking” the stage and sliding the stage left or right. Use this for coarse adjustment of the
X- axis.
After locking the stage, use the knob on the right for fine adjustment along the x-axis up to 0.5
inches.
Each adapter bracket has its own individual z- axis adjustment. The DE3200-S2 the bare fiber
stage can be adjusted along Z-axis using the thumbwheel towards the bottom of the stage.
The Y- axis adjustment is controlled by the focus knob on the both sides of illuminator base.
Changing Adapters on the DE3200:
Adapters on the DE3200 Series stage can quickly be changed out by loosening the two thumb screws.
When aligning the adapter 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. This minimizes the amount of focusing required when switching connector
styles.
Setting APC Adapters on the DE3200:
Use the two end positions on the DE3200 Series stage for setting up APC 2.5 or 1.25mm adapters. A
third mounting hole is provided to angle the adapter at 8 degrees. Insert the connector key up on the
left hand position and key down on the right hand position.
As with setting up any adapter 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.
Changing Bare Fiber Adapters on the DE3200-S2:
There are a few different bare fiber adapters for the DE3200-S2 to best accommodate your fiber viewing
needs. The bare fiber rotator allows the operator to turn the fiber 360°, currently this is only available

for 1.25mm and 2.5mm fibers. The Quick Release V-Groove allows the operator to switch between
multiple fiber sizes, this adapter allows for fiber sizes from .125mm to 2.66mm.
These adapters can be switched out for different applications by following the diagram below:
Preventive Maintenance
Caution:
The following instructions should only be performed by qualified service personnel.
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.

General Cleaning
Harsh solvents are not recommended on a regular basis. Typical safe degreaser solvents can be used to
clean old grease or grime from mechanical parts. Ordinary 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 DE3200 Series 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 may
require the operator to re-center the fiber optic bundle over the vertical illuminator.
1. Using a 1/16” hex wrench, loosen the three set screws at the top of the Vertical Illuminator.
2. While viewing a fiber on the monitor, slide the fiber optic bundle and adapter until the greatest
amount of light is over the cladding area of the fiber.
3. Re-tighten the three screws.
Note: adjust the light intensity up and down to confirm the light is centered
Cleaning objective lenses
Oils, dirt, and fingerprints may reduce the resolving power of the objective lenses. To ensure maximum
levels of performance of the DE3200series microscopes, 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.
Adjusting the Magnification
A slight adjustment to the magnification can be made by turning the video coupler. This essentially
alters the tube length of the microscope and may cause some of the objectives to loose parfocality,
however it is a handy adjustment when calibrating the microscope to specifications that are slowly being
introduced into the industry.
