Need Optical Quality Plastics
(OP)
I am looking for optical quality plastics. I need a suitable material to build a 21" dia and 0.5" thick window that will provide good photographic images without much distortion. Any suggestions or recommendations???
Thanks,
Leonard.

The motionnet links were pretty useful, but for some reason the Wavelenght Optics link isn't the safest thing to link to at work.

Common acrylic is one of the clearest plastics available (in the optical wavelengths). A bonus is you can get it in all kinds of thicknesses and it machines like a dream. I suspect that 1/2" is way to thin for a 21" window if you want it to stand up to vacuum. A quick calc in my head says 2-1/2 tons of force on the window.
