Holographic Imaging?

Rich Hibner · November 13th, 2006, 11:16 AM

Yeah, I thought the 20degrees looked to be the most viable one. I think 15degrees might have something going also. And it would be fancy to have a .010 or .015 at 15 to 20degrees to see the difference in diffusion, bokeh and grain. I wonder what the multiple degree angles are? Say 75x30degrees? It's just getting too complicated. I saw your letus clip. Hard to tell with so much compression. I sent you my mailing info.

This is an engineering diffusion company that sent me a .pdf of what angle degrees do.

Give a better idea.

Yeah, that is the reason for the triplet (to reduce chromatic distortion) relay lens (achromatic macro condenser) to relay the image down to the target aperture reducing the hot spotting. It is likely to be a lot better for image quality compared to a Fresnel lens (unless it is a very very good one). But yeah, the grain, what is that about, I'm pretty sure the beattie has none, just resolution problems?

Thanks

Wayne.

Here are some other interesting diffusers:

I'm looking to buy a holographic diffuser, but don't want or need to spend 110.00 on a 2x2 sheet. Anyone else here interested and can go half on it. I don't know exactly how to go about it to make it secure and so no one thinks I'm trying to make a quick buck, or lose money either. So post here or PM me. I'm looking to get the 2x2 15degree or possibly a 20 degree sheet. I only need/want 1x1.
