VPFC Series IR Windows


Crystal Infrared Windows

VPFC Series (Viewing Pane Fixed Crystal) IR windows are specially coated to reduce the 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 unconditional lifetime warranty. The transmission rate characteristics of CaF2 are suitable for higher temperature applications, shortwave and midwave thermography and for the visual spectrum. Medium to longwave transmission rates (7-14 micron) are typically between 40-50% based on the infrared (IR) camera detector sensitivities at different wavelengths.

VPFC Series Features

IRISS IR windows are the most certified windows in the industry with IEEE (impact & load), UL, cUL, Lloyds, CSA 22.2 14-13 for industrial control equipment. Our marine certifications are Lloyds, DNV and ABS (American Bureau of Shipping) credentials. IRISS IR windows are also arc tested to IEC 62271-200 Arc Flash Spec test 1.1 Second Duration, IEC 60262271-200: 63kA, IEC 60298 Appendix: 63kA, IEEE C37.20.7 Type 2B: 63kA,

The IRISS Unconditional lifetime warranty is unique in the IR industry as it not only applies not only to the workmanship of the window housing but also applies to the durability and stability of the optic in the proposed environment. No other manufacturer can offer this because crystal optics will fail over time, and are only able to at best offer a limited lifetime warranty for manufacturing defects

IRISS manufactures and assembles all products at our global headquarters located in Bradenton, FL.
