This rear-projection screen is a high-contrast diffusing screen made of glass. But ProFess differs from conventional rear-projection screens:
- the ProFess screens consist of glass and are thus a lot more stable and durable.
- the surface can be written on - even permanent markers do not cause any lasting damage.
- due to the laminated glass, security modifications regarding statics, breakage and fire protection do not produce any problems
- a special contrastive foil allows a pin sharp picture
- no hotspot or other picture impairments
In order to use the ProFess screen as a whiteboard at the same time, it has to be illuminated by a homogenous source of light or by a projector from the back side.
Unlike our holographic screens, ProFess is not based on holographic light redirection and it is also not transparent. Its daylight suitability is good, but more limited than HoloPro™.
Standard sizes are 20", 30", 40", 50", 60", 67", 84" und 100" in 4:3 format.
