Looking for polymer that transmits infrared and visible spectrum
Looking for polymer that transmits infrared and visible spectrum
(OP)
I have a need for a polymer that will transmit infrared and visible spectrum. I have an Electrical background so I could use some expertise in this area. Any help identifying a source for this polymer or an approach to source it would be appreciated.

Saran Wrap seems to work OK for some applications.
You haven't said what other requirements are imposed.

Usually I'm thinking in cm-1 when it comes to IR due to time on FTIR instruments...
Can you live with 8~13.5um? Polyethylene(PE) is pretty darn clear in that region, but has some strong bands from 13.5-14. Some PE crowds a bit on the 8 end as well. If I recall correctly, HDPE is better on the 8 end.
PE is the best I can come up with for a common organic polymer.
I don't suppose you could use a crystal like KBr, Germanium or sapphire... those are commonly used as FTIR windows and/or lenses.
