How Wide?

[Insanity]

Just playing around in my living room with a camera lens on my greenie for a bit of fun and here is the result...

Pics are in daylight and taken in a very small room, no adjustment was made to scan angles, all at 30 degrees...

Nice result Mark.

Looks like you got a bit of internal reflection off the lens groupings on the circle pattern but otherwise it looks pretty much perfect. The Perperanni man looks totally undistorted.

How does it work at beam level?

[Insanity]

There are a few artifacts from the lens, but when the beams are moving it is negligable and you probably wouldn't notice in a bigger room, the projector was about 6 feet away from that wall... And a small price to pay for 120 degree fans and tunnels

If you fire a single beam through it, you still get a single beam. But when it moves it really fills a room easily..

Don't think it would be any good with more than one colour going through it though. My guess is that the colours in an image would separate, due to differing focal lengths...

Cheers

Be interesting to try it on your 1 Watt White Light.

Unfortunately my 1 watt whitelight is no more

I have been in the process of upgrading it to a 2 watt for some time now... Just waiting for the new blue and green to arrive... So at the moment it is no more than an empty case... I'm missing it badly, but the new one will be worth wating for, all beams will be the same profile, thanks to a certain 640nmm red

very neat! what kind of lens?

I've seen a few times, people talking about increasing scan angle with a lens. But always in one color. I wonder if a achromat would hold the colors together.
