Any Camera - Any Task

Any Camera - Any Task

The exclusive industrial-grade, reinforced polymer optic allows any thermographic camera to monitor completely undisturbed assets inside electrical equipment. The IRISS Polymer optics work with all ranges of Infrared, Ultraviolet and Visual Inspection Cameras.


Environmentally Sealed Design

The VPFC Series of products are constructed from switchgear grade Nylon plastic with an aluminum cover and stainless steel mounting screws. Seamless custom gaskets ensure the NEMA4 / IP65 ingress protection rating is maintained.

Tested and Certified to The Highest Industry Standards

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.

Proudly Made in the United States

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

Protected by our Limited Lifetime Warranty

The IRISS Limited Lifetime Warranty protects against any manufacturer defects for the life of the product. However, as with all other manufactures of crystal IR windows, the optics as all crystal optics will degrade and fail over time.
