5.1.3 Cleaning the Lens
To optimize image quality it is recommended that any lens used with the VersaDoc be
cleaned before it is installed in the system. Both sides of the lens should be cleaned using an
optical cleaning solution and optical tissue. Avoid touching the glass surfaces of the lens
when installing it into the instrument, as fingerprints will effect image quality.
5.1.4 Cleaning the Emission Filters
To optimize image quality it is recommended that the emission filters installed in the
VersaDoc system are periodically cleaned. Both sides of each emission filter should be
cleaned using an optical cleaning solution and optical tissue. Avoid touching the glass
surfaces of the filter when installing it into the instrument, as fingerprint will effect image
quality.
5.2 Replacing Lamps in Illumination Sources
The life of the broad wavelength UV lamp is approximately 500 to 1000 hours, depending
upon use. As the lamp ages, the required integration time will increase because the intensity
of the UV emission will diminish. If the integration time for image acquisition has increased
more than three-fold, it is recommended that the lamps be replaced. The life of the white
light lamp is approximately 1000 hours.
NOTE: THE LAMPS SHOULD BE REPLACED IN PAIRS FROM ALL ILLUMINATION MODULES.
5.2.1 Replacing the Lamps in the Transilluminator Module
To access the lamps in the transilluminator follow the procedure outlined below.
Caution:
Do not touch the glass parts of the lamp or lamp housing. Fingerprints on the
lamp may result in non-uniform illumination. The use of power-free latex gloves is highly
recommended.
Tools required: You will need a #2 Phillips screwdriver and 5/16 size socket wrench to
change the lamps in the transilluminator.
To change the lamp, follow the procedure outlined below (Figure 5.1):
1. Turn off the power to the system.
2. Open the main door to access the UV transilluminator cable.
3. Disconnect the UV transilluminator cable from the ballast assembly.
4. Slide the UV transilluminator module on the slides out completely.
5. There are two release levers on each rail that are made out of black plastic. Pull the
transilluminator module out while pressing down on the lever on the right side and lifting
up the lever on the left. This will allow you to completely disengage the slide rails from
