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.
The micrometer nut
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.
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.
For more information on magnification or calibration, please 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.
This adjustment is relative to the size of the image and will not offer any more or less resolving power to the microscope.
Cleaning the CCD Camera
Use extreme caution when attempting to clean the camera. Any scratches, solvent, streaks or dirt left on the IR filter of the CCD will show up in the field of view of the microscopes.
Before attempting to clean the IR filter on the CCD 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 CCD camera on the Microscope.
Due to the orientation of the CCD, if the dirt remains in the same spot and does not rotate with the camera, the dirt is most likely 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.
Caution: Blow air across and not directly at the CCD sensor of the camera.
Adjusting the knob tension on the DE3200 Series
The tension on the X-axis adjustment knob may need adjustment from time to time depending on the frequency of use.
1.
Using a .05” hex wrench, unscrew the locking set screw that secures the knob to the drive shaft and remove the knob.
2.
Using a spanner or special adjustment tool available from Domaille Engineering, LLC. Adjust the spanner nut clockwise to increase the tension on the knob. Likewise turn the spanner nut counterclockwise to decrease the tension.
Troubleshooting Advice
Image is Not Clear
No Illumination
No Video Image
Image Not Centered
Spots and/or Lines on the Monitor
Loss of Resolution or Image Contrast
Try adjusting the focus mechanism to bring the image into focus.
Increase or decrease the light intensity on the fiber optic light source.
Adjust to 5x objective and verify fiber is in the field of view.
Check the set-up, confirm that all connections are made and that everything is powered on.
Increase the light intensity on the fiber optic light source.
Check the fiber optic light source, replace it if necessary.
Check the set-up, confirm that all connections are made and that everything is powered on.
Re-set the light intensity to approximately half power, too much light will bleed out the image resulting in an all-white screen.
Try adjusting the focus in and out.
Use the Z-axis stage adjustment and the linear slide knob to bring the fiber to the center of the screen.
Fine tune the adjustments on the Z-axis using the knobs on top of each bracket.
Slightly decrease the contrast control on the monitor as this may enhance optical interference with the CCD Chip.
Check the CCD Camera of dirt and debris.
Isolate the scope from other electronic devices that may cause video interference.
Check the objective lenses for dirt, scratches or film.
Adjust the brightness and contrast controls on the monitor.
Make sure the impedance switch on the back of the monitor is set to 75Ω.
Check the CCD camera for dirt and film.(Add period)
Make sure the shutter on the CCD is set to the OFF position.
Tighten the focus tension knob. Image Drifts In and Out of Focus
Tighten the side adjustment screw on the connector bracket.
Image is Not Centered Between Objectives Check that each objective is screwed on tight.
