Greetings
Try http://www.edmundoptics.com I have
purchased many different mirrors and lenses from them for our department at
reasonable prices.

Hi all -
Does anyone know of a source for decent converging mirrors? I need several
~30cm focal length, ~15 cm diam (f/2) mirrors for creating images on
screens. They don't have to be super fancy (e.g. I don't want front surface
mirrors), just good enough to make nice images. I've tried buying "make up
mirror" type mirrors, but even the ones I got that said "optically correct"
have made crummy images.
thanks,
John
