Durable and Rugged

Polymer based IR windows are far more able to resist the mechanical stresses applied to IR window that are fitted to electrical distribution equipment. It was IRISS that first came to market with industrial grade IR windows that could meet the mandatory impact and load testing requirements of UL, CSA, IEEE, IEC, CE testing that could never be passed by any crystal based IR window.


There is no such thing as a standard IR inspection so why should there only be a standard IR Window? IRISS is the only IR window manufacturer with solutions for unique applications. The patented IRISS reinforced optic is flexible and can be manufactured in an infinite number of shapes and sizes ensuring that the FlexIR Custom IR window meets your needs and applications.

Protected by our Unconditional Lifetime Warranty

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.

Proudly Made in the United States

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