Cleaning the optical surfaces
Some of the optical surfaces in your PowerVX system are made for very high reflectivity,
such as mirror surfaces etc. Reflectivity of more than 98% is obtained only, if the mirror
surface is free of dirt or fingerprints. Also, lenses and filters depend on a clean surface for
maximum efficiency.
Unfortunately, a cleaning of the silver mirrors in your PowerVXis only possible once or
twice. Since the optical section is dust free and also air free, there should not be any
contamination of these mirrors. During alignment process, and any time, the case top is lifted
or unmounted, please make sure, to work in a clean environment with minimum dust
particles. The lesser your particles, the better your results. In the unlikely case of a dirty or
contaminated mirror surface, you can try to clean the mirror with simple glass cleaner and a
very mellow paper tissue. Do not use any alcoholic cleaner such as Acetone or Methanol! If
cleaning is not possible, the mirror has to be exchanged.
Other optical coated surfaces can be cleaned the same way, with standard glass cleaner and a
mellow paper tissue just as Kodak Lens Paper. Make sure not to leave any traces of the
cleaner fluid on your surface. Do not rub or press on the surface of the mirrors.
Color filters can also be cleaned easily, since the coating is much harder than the ones on the
mirrors. Make sure to avoid any rough treatment.
Connections and adjustments
The rear panel of the PowerVX shows several connectors and adjustment features. Main
control of the projector is the ILDA compatible connector. It supports full RGY and
differential XY signals. The pin connection is described on the back of the PowerVX, here is
