Infrared Lenses for Camera Series VarioCAM® High Definition
f/1.0 Precision Infrared Lenses
The f‐number f/1.0 precision infrared lenses, used for the uncooled camera series VarioCAM® High Definition, exhibit an extremely high IR transmission and prevent undesirable image inhomogeneities and imaging errors such as vignetting and distortion etc..
The quality of the lenses is an important criterion that contributes to adequate radiation reaching the detector, even in case of low lens temperatures, creating low‐noise images with reliable measured values. In this way, a high thermal resolution of 0.02 K is achieved, which results in outstanding image quality and detail accuracy. A comprehensive lens assortment covers the range of potential measured objects from micro‐thermography to telephoto applications for measuring objects at a great distance. The lenses of the VarioCAM® HD camera family are conceived as uncompromising complete lenses with the opening number 1.0, maximum transmission and transfer volume as well as minimum distortion.
A special, highly resistant DLC (Diamond like carbon) coating protects the optically active surfaces of the lens even under harsh conditions. Extensive measuring objects such as photovoltaic systems can also be thermographically measured reliably and efficiently, such as objects requiring safety distances, as in the case of high‐voltage installations. When changing a lens, this is detected automatically by the camera and the stored calibration data is loaded.
