Need plastic transparent to Infra red





2003

My company develops long range outdoor infra red detectors. Our biggest challenge is to find material around 100x100 mm which is transparent to Infra red and isn't expensive. I know that some kinds of plastic are 50% transparent, but we must find something better. The material has to be transparent to IR only ( 8-14 um).

Please advise,

You have not specified how much transmittance you need from plastics. The infrared industry typically does not utilize plastics for infrared applications due to the reflectance and interference issues. I would suggest looking into Germanium which is the best material for your application.

Best of Luck,
