The V412BD infrared (IR) viewing window includes a 4" x 12" viewing pane and integrates our patented composite safety optic along with the BLASTDOWN® pressure relief system for arc-flash protection. This combination ensures exceptional safety and flexibility.
The ViPIRS V412BD incorporates a next-generation composite polymer optic that is fully compatible with the latest thermal imaging technology, offering an exceptional field of view and image clarity through its mesh-reinforced polymer composite. Traditionally, infrared viewing panes with transmissive polymers required metallic mesh on one or both sides of the polymer sheet to meet safety standards. This dual-mesh setup often led to issues with image clarity and vignetting effects due to misalignment and angled imaging.
Unlike traditional IR windows that depend on 'arc containment' for protection, the ViPIRS range features a distinctive BLASTDOWN® arc-flash pressure relief system. Instead of trying to contain the intense overpressures produced by an electric arc flash, the ViPIRS BLASTDOWN® system directs the energy through specific vents located at the base of the frame.
The ViPIRS V412BD composite optic features a single mesh embedded within the polymer, resulting in a durable infrared transmissive optic that meets the latest codes and standards without the image distortion problems associated with mesh alignment. With smooth surfaces on both sides, the V412BD is easy to clean and maintain, ensuring optimal image quality and a wide field of view.
Certified by Underwriters Laboratories (E516454), the American Bureau of Shipping (21-2156486-PDA) and ExVeritas (21TEST0933) for both indoor and outdoor installations into NEMA 250-rated Type 4/12 equipment and EN60529:1992 + A2:2013 IP54-rated equipment, this infrared viewing pane complies with the latest industry standards, including IEEE (impact and load), UL50V, UL746C and UL94.
