The Omega Optical package containing the kit arrived in my mailbox.
I haven't tested them on my projectors yet, I just picked them and tested them looking through my window.
The extinction is really impressive compared to polarising filters, however the most impressive thing was that colours through the filter look identical to unfiltered (only reduced brightness), you have to angle the filter significantly to see colours being changed. A few years ago, I tried the same with Infitec glasses and the colours were significantly modified, and different between the two eyes, which doesn't happen with the Omega filters. So far, so good.
Now, this was just a quick test with natural light from outside, I'll now have to see if it still works with the light coming from the LCD projectors. I'm optimistic but I'll test that later, I first need to figure out a simple way to temporarily hang the filters in front of the projectors, and then find a more practical and permanent solution.
The glasses seem to be comfortable on the nose, they do reflect my eye quite a bit (but that's in the day light), I'm surprised by the behaviour of interference filters :
I'm used to absorption filters which blacken the filtered light, interference filters reflect back the filtered light like a mirror.
There's juuuust one thing about the glasses.... the style. They REALLY look dorky, its fine for 3D fans like us and for a first batch but your next step will really be to figure out a way to make decent looking glasses, because some people I know will never dare to wear them.
