Infrared wide-angle lens features environment-resistant coating for thermographic cameras
Its innovative hybrid DLC (“Diamond Like Carbon”) surface coating protects the high-quality optics when used under extreme ambient conditions. A large 135° x 100° field of view enables measurement and surveillance of large objects – even from a short distance. The high-resolution thermographic cameras VarioCAM HD and IR-TCM HD, for which the lens was manufactured, are used for a precise measurement of smallest thermal object details and hot spots; the series’ clear advantage is the image resolution of up to 3.1 infrared megapixels when using the 7.5 millimeter wide-angle lens. Stationary IR-TCM thermographic cameras for industrial use, in particular, have to resist severe endurance tests because rough ambient conditions and process-related influences may affect camera and optics. While people wear safety goggles to protect their eyes under such conditions, the infrared optics of the thermographic camera is protected by a newly developed coating. The new hybrid DLC coating combines the durability of a diamond coating with an improved transmission and multispectral functionality of a dielectric coating thus guaranteeing optimum reproduction.
