Cleaning the optical surfaces
Some of the optical surfaces in your AttaXX 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 AttaXXis 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 AttaXX shows several connectors and adjustment features. Main control
of the projector is the ILDA compatible connector. It supports full RGB, differential XY
signals, and automatic switching between ILDA connector and internal player board, or LAN
board, if applicable. The pin connection is described on the back of the AttaXX, here is a
summary:
