Hi. I am looking for any thoughts on the size and shape for the filters on a dual projection passive 3D system. the actual image size that passes through a lens is of course smaller than the lens diameter.
I may be altering the Omega 3D dual projector kit we are selling to optimize it for use on higher end projectors. the passive filters will be the same but the usable size and mount may change some. the filters are currently 55x35mm with a 52x32 usable aperture
as these filters are complex metal oxide thin film technology the size or area of the projection filter is important in terms of cost.
the Beta kit offered may change and possibly the pricing. it would be great to get some feedback on the kits from those who buy it.
for those who have not seen the youtube video ( we are making a new one ) here is the demo of the kit. thanks

so basically , it is the same as the dolby 3D (patent issues there)
Looks good for the price, since dolby filters are awfully expensives, either on glasses or profectors.

Hi actually they are only similar in a small way to dolby not the same. Totally different approach in terms of how the spectrum is split. Infitech splits rgb into two each . Omega 3d splits the visible spectrum into two sets of spectrum evenly over the entire visible range making for spectrally and energy balanced sets utilizing many more bands. Not a patent issue. It's been checked in detail for that issue. Our approach dose not require color correction lending itself to far easier implementation on a wider range of applications. And its far more economical.
