DE8800 Series
Fiber Optic Inspection Scope
User’s Guide
Overview
Manufactured by Domaille Engineering, LLC, the DE8800 Series
Video Microscopes are designed for high quality visual end-face
inspectionofberopticconnectorsinaresearchorproduction
environment. This scope has a unique stage with inverted optics
allowing the operator to inspect connectors, without removing
themfromthepolishingxturetherebyincreasingthroughput
during inspection.

Mounts the camera to the microscope base by bending
it out of the way of the operator.
High resolution monochrome which are standard
components of the DE8800 series microscope.
Additional camera options available, contact
Domaille Engineering for details.
Avarietyofinsertsareavailabletotawiderangeof
polishingxturesfromseveraldifferentmanufacturers.
Providesacenteringadjustmentforthepolishingxture
and allows transvering of Multiple Fiber Connectors.
Provides a side to side centering adjustment on the
monitor and allows the opertator to quickly scan MT
style connectors for defects.
Transmits light from the light source to the vertical
illuminator.
Acourseandnefocusadjustmentarelocatedon
each side of the focus unit. Turning this knob towards
the operator will bring the optics closer to the stage.
High quality Long Working Distances Lenses are the
primaryfactorwhendeterminingmagnicationand
resolution. Standard models are equipped with:
ME-120065x
ME- 12007 10x
ME- 12008 20x
Optional 40x and 3.3x objectives are also available.
Mounts the objectives to the base of the microscope.
By turning the nosepiece the operator may quickly
changethemagnicationofthemicroscope.
Protective covering that prevents dust and debris from
obstructing the optics.
Mounts the Fiber Optic Bundle to the Light Source
Base. Also mounts the beamsplitter which directs the
light toward the stage.
Mounts all the light components. Two screws located
on the sides provide centering adjustment.
Slight X-axis adjustment that moves the image up and
down on the monitor’s screen.

Initial Setup
After unpacking the DE8800 series
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 supply/LED Controller, and
monitor (or personal computer
using a frame grabber or
digital camera).
The ME-12013 LED/ME-12015 Controller operates from a 24 volt
DC output power adapter (ME12015) 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 CCD camera and the
illumination of the microscope.
Weprovidetwodifferentmonitortypes,inseveraldifferentsizes.
Thesemonitorsarehighresolutionmonitorsspecically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sufcient.Acomputermayalso
be used to capture images, contact Domaille Engineering for more
information on digital camera options or video frame grabbers.
Features
• High Resolution video and CCD camera, digital cameras also available.
• Four Position Nosepiece with 5x, 10x, and 20x LWD objectives.
• Long Working Distance Optics for UPC and APC inspection.
• An extensive range of inserts, reference pages 14-15.
• Precision illumination Control.

• Precision illumination Control.
Lighting
The illumination can be controlled using
the “On/Off LED Intensity” control knob
(Dark grey 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bercladding
andhighlyreectivemetalorceramic
ferrules. A dimmer switch button is
also provided for this function.
Clockwise = Increases Illumination
Counter-Clockwise = Decreases Illumination
ChangingMagnications
Each DE8800 model is equipped with
three LWD objective lenses: 5x, 10x,
and 20x. The objective lenses are
mounted to a microscope turret
or nosepiece allowing the operator to
quicklychangemagnicationswhen
inspecting connectors. Optional
objective lenses are also available
in 3.3x and 40x.
Operation
Focusing and Focus
Tension Adjustments
The Focus Adjustment Knob on the
DE8800 series is conveniently located
on each side of the base. Both course
andneadjustmentareprovided.
A tension adjustment is also located
on the right side of the scope.
Clockwise = Focuses the Stage Out
Counter-Clockwise = Focuses the Stage In

DeterminingActualMagnication
Thebestmethodtocalculatetheexact“total”magnicationused
ontheDE8800seriesistomeasurethediameteroftheber,
cladding on the video display. Take the measurement in millimeters
anddividethatamountbytheactualsizeofthebercladding,
typically 125 micron. The result is the “total” optical and video
magnicationbeingused.
For example: taking a set of calipers, we measured the diameter of
the ferrule viewed through DE8800 on a monitor to be approximately
53.49mm.
Actual size on display/cladding diameter in mm = total magnication
53.49mm / .125mm = 427.92X
Linear Stage Adjustments
The stage on the DE8800 has three adjustments. The polishing
xtureinsertrotatestoviewnewconnectorsmountedonthe
polishingxture.Mostinsertsfeaturedetentsthatallowthe
operator to stop rotating precisely over the next connector.
Y-axistravelisprovidedtoscanmultipleberstyleconnectors
and a X-axis adjustment is provided to center the image
on the monitor.

Changing Inserts
All inserts, except DE8134, simply lift up and out of the stage
assembly. This enables operators to quickly change inserts to
accommodate different types of connectors when inspecting
jumpers with different types of connectors.
The DE8134 12 position insert for Domaille and Seikoh Giken 510
polishersisxeddirectlytothestageassembly.Useahexwrench
to loosen the release screw in the back stage.

Preventive Maintenance
Caution:
The following instructions should only be performed by
qualiedservicepersonnel.
Warning:
Ifequipmentisusedinamannernotspecied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 DE8800 series microscopes are relatively low maintenance. Basic care
and precaution in using the instrument is required. Depending upon the cleanliness
of the general working area as well as the age of the equipment, we would suggest
at least semi-annual service and maintenance.
