Maintenance
General Information
When not in use, the accessory should be stored in the antistatic bag provided in a controlled
environment. Dust and moisture may adversely affect its performance. Take the following pre-
cautions when using your RSA-PE-20 accessory:
• Never disconnect or connect the detector cable with the instrument powered
ON
• Do not handle the mirrors without gloves
• Do not allow foreign objects to enter the integrating sphere
• Clean dust and particulate debris out of the sphere using a gentle stream of
clean air.
Mirror Cleaning Procedure
The transfer optic mirrors should never be touched or handled without the benefit of gloves. The
mirrors have a protective magnesium fluoride overcoat to allow cleaning if necessary. The fol-
lowing cleaning procedure is recommended:
1. Spray the mirror with Fantastic Spray Cleaner.
2. Rinse the mirror with distilled water.
3. Repeat until the water sheets off the mirror.
4. Blow dry with a stream of clean nitrogen.
Spectralon Cleaning Instructions
In order to maintain the unique optical and reflectance properties of Spectralon standards, keep
the surfaces of the material very clean. Should Spectralon become soiled, particles may be blown
off it with a jet of clean air. If this is insufficient, sand the piece with a 220-240 grit emery cloth
under a stream of running water. Sand the surface until it is totally hydrophobic (water beads and
runs off immediately) and then shake off water droplets, or blow them off with a stream of clean
air. You will have to disassemble the integrating sphere to do this.
Note:
Ordinary compressed air systems typically carry microscopic oil droplets that may con-
taminate Spectralon.
