Not much known, yet. Demoed in Chigaco beginning of this month at a bi-annual planetarium conference. On-Off is much higher than any CRT projector. Press releases and so posted at avs (the wrong section, as you can't get anything at Carl eiss for under 20K US list;-))

So I take it this projector is aimed for commercial applications rather than home theatre?

Yup, Gino, see the release I posted at AVS. Initial optics are specifically designed for dome projection, but they keep an open mind suggeting other uses like simulation.

those numbers are HUGE!! I wonder if they use laser as the light source. I am looking forward to hearing more about this....

2,500,000:1 contrast ratio, yow. That's like pitch-black up to phasers-on-stun.  Seriously. That's like 100 ftL -- which is enough to look very bright in a brightly-lit room -- down to 0.00004 ftL, which is way darker than you can see after sitting in the dark for an hour. Wikipedia says the dynamic range of the human eye is 1,000,000:1, so this thing has more contrast ratio than the human eye can see!
I assume that's the on/off contrast. I don't think you could get ANSI contrast that high unless you projected in a vacuum!!

Nope Zeiss already has a scanning LASER system. These use 'lamps' in a 'lamphousing'.

so this system uses a remote light source, has 30bit colour, uses TI "Brilliantcolor" ( combination of RGB and CMY on a DLP system) and is capable of 1200P (3K or 4K)... it needs a proprietary computer to drive it and has a 6.4Kw power draw..... unless I build a home planetarium (after winning a lottery...) I really doubt that the trickle down on this will be any more accessible than other Zeiss planetarium projection gear.
