Cal Sensors has announced the launch of a new line of single channel detectors (SCD) that block unwanted radiation below 1.2 microns. Exploiting the innate transmission bandwidth of Silicon, the new SCD-Si detectors are packaged with anti-reflection Silicon windows to block undesirable energy in the UV and visible spectrums. Thus these detectors focus on the infrared spectrum, minimizing the effects of unwanted radiation that can interfere with test results and reduce measured dynamic range. Optimizing performance in the 1.2 to 5.5 microns infrared spectrum, the SCD-Si detectors combine the superior sensitivity and fast response-times of lead salt detectors with the band-limiting attributes of Silicon to provide excellent quality, long life and high performance detection.
Anti-reflective (A/R) coated Silicon is readily available, robust and can be designed to optimize the transmission in the near to mid-IR spectrum. It is an ideal material for filtering the radiation that hits the detector in the 1.2 to 5.5 microns operational bandwidth.
