Detector for FTIR applications
Newly developed type PCI-2TE-13 photodetector designed and optimised for FTIR applications. This new detector has a wide, 1 to 13 µm, spectral bandwidth and broad linear output range. Detector's responsivity is stabilized with built-in two-stage Peltier cooler, keeping the sensitive element at temperature 220 to 240 K. Performance of the devices has been improved with heterostructure design, optical resonance and hyperhemispherical immersion. Constant voltage bias and current readout should be used for the best performance and linearity. The spectral characteristics of the detector can be modified according to specific requirements. Standard detectors are available in modified TO- 8 packages with BaF2 windows. Other packages, windows and connectors are available upon request.
