Iriss VPFC-50 2' Crystal IR Window

Research-grade IR window;  2" (50mm) viewing pane diameter

The VPFC Series (Viewing Pane Fixed Crystal) IR windows are specially coated to reduce transmission drift due to moisture/humidity. However, industrial users are strongly encouraged to investigate the VPT Series of industrial-grade IR windows, which are specifically designed for stability in harsh industrial environments and have an limited lifetime warranty. The transmission rate characteristics of CaF2 are suitable for higher temperature applications, shortwave and midwave thermography, and the visual spectrum. Medium to longwave transmission rates (7-14 microns) are typically between 40%-50% based on the infrared (IR) camera detector sensitivities at different wavelengths.
