Meet the CAP -V Series.  IRISS is the first to design and bring to market this innovative dual view infrared window. This original innovation by IRISS is the most certified dual viewing window in the world.  The CAP-VC features the largest dual view visual and infrared (IR) viewing areas available on the market today. The CAP-VC visual viewing pane is constructed using Makrolon® a load resistant, glass fiber reinforced polycarbonate allowing for quick and easy visual inspections to be performed. The CAP-VC IR viewing window features our exclusive pharmaceutical-grade reinforced opaque polymer allowing any thermal camera to monitor your critical assets completely undisturbed inside energized electrical equipment in the shortwave, mid-wave and longwave IR spectrums.

The larger rectangular viewing area provides an unparalleled field of view when compared to traditional round IR windows. The CAP-VC offers full or half locking covers, useful in areas of high traffic and protect the visual and IR viewing panes from impacts, flying debris and dust. As well as optional full sized ultrasound inspection port or ultrasound sensor allowing you to safely and easily perform ultrasound and partial discharge inspections.
