Optical properties of Acrylic at elevated temperatures
Optical properties of Acrylic at elevated temperatures
(OP)
I am in a situation where I have a 40mm thick piece of Acrylic between two polarizers. My problem is that the acrylic turns birefringent at around 35 deg C, and optical performance is badly degraded. I have contacted Ineos about Perspex, but it is not available in the right thickness in the US. DOes anyone know of a material with similar optical performance (>90% transmissivity, ~1.5 refractive index, with superior thermal characterisitcs.
Thanks
Andy
