Optical detector PC-3TE-10,6

semiconductordynamicIR

PC-3TE 2-13 μm IR PHOTOCONDUCTORS THERMOELECTRICALLY COOLED The PC-3TE-λopt photodetectors series (λopt - optimal wavelength in micrometers) feature IR photoconductive detector on three-stage thermoelectrical cooler. The devices are optimized for the maximum performance at λopt. Cut‑on wavelength is limited by GaAs transmittance (~0.9 µm). Bias is needed to operate photocurrent. Performance at low frequencies (<20 kHz) is reduced due to 1/f noise. Highest performance and stability are achieved by application of variable gap (HgCd)Te semiconductor, optimized doping and sophisticated surface processing. Custom devices with quadrant cells, multielement arrays, different windows, lenses and optical filters are available upon request. Standard detectors are available in TO8 packages with wZnSeAR windows.. Other packages, windows and connectors are also available. Features: - High performance in the 2 to 13 µm spectral range - Fast response - Convenient to use - Wide dynamic range - Compact, rugged and reliable - Low cost - Prompt delivery - Custom design upon request Parameter: PC-3TE-10,6 Material: MCT Type: Non-immersion Cooling: Three-stage Wavelength/ λopt/ µm: 10,6 Package: TO8, TO66 Window: wedged ZnSe AR coated Detectivity/ D∗/ cm⋅Hz1/2⋅W−1: ≥2,5x108 Time constant/ τ/ ns: ≤20
