Ebay #8253471228

100 Grooves per Inch
350mmx270mm

So now we have sources for:

220mm
330mm
550mm
600mm
650mm

I wish someone would fill the blank of 450mm.

I'd use it with my many lenses.. I'm building a variable focus projector. Maybe I the 330mm will suffice for short throws but it just seems like agood idea to fill the hole at 450mm.

OK, I understand I was wondering if it was filling a hole or if you had some SECRET plans

The "other" DIY projector site had a group buy of 450mm fresnel that were being custom made. I guess you could e-mail the proprietor.

According to the auction you can put that fresnel on your computer screen, and become immersed in a 3d world?!!

Yeah, you can try that with any fresnel, place it a few inches away from your monitor while playing a Flight Sim, it gives the impression of depth.
