CAP-ENV Series
The Toughest and Most Reliable Infrared Window in The World
The CAP-ENV features a reinforced, environmentally-sealed door design, while also providing the largest visually-clear infrared (IR) transmissive viewing area available on the market today. The exclusive reinforced-polymer system allows any thermography camera to monitor completely undisturbed assets inside energized electrical equipment on the visual, UV and shortwave, midwave and longwave IR spectra. The larger rectangular viewing area provides an unparalleled field of view when compared to traditional, round IR windows. Constructed completely from stainless steel, the CAP-ENV series is recommended for outdoor applications.
Unparalleled Field of View
Unlike the round infrared windows the large format IRISS CAP-ENV Series and custom infrared windows have a far superior field of view. The CAP-ENV Series has a large FOV which gives the thermographer the ability of infinite viewing angles inside the switchgear.
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.
UL Listed
Large format replacement panels like the CAP-ENV Series are now UL Listed replacement components (UL File E 491496). The CAP-ENV Series has an oversize Field of View (FOV) giving the thermographer infinite viewing angles within the bus system.

Tested and Certified
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,

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

Fixed and Stable Transmission
The polymer IR window systems will maintain fixed and stable transmission (FAST) for the life of the installation ensuring that the temperature data collected through the IR window is accurate and reliable for the whole life of the installation.
