| 概述:
The FTIR-OEM100 is an infrared detector module designed to operate in conjunction with the FTIR-OEM000 interferometer module. The detector module has internal optics to focus a collimated baem onto the detector active element. The 2-stage cooling of the MCT detector is driven by a PTEC controller and 4 different gain levels can be adjusted on the detector amplifier. Detectors with spectral ranges up to 12 microns are available.  规格参数:
