A number of standard packages available. See the PbS and PbSe sections for specifications and illustrations.
Opto Diode offers a variety of TO-style and other packages for the detector(s), cooler, integral optical filter(s) and detector signal processing electronics.
TO-style and other standard semiconductor packages are of welded construction, hermetically sealed and typically backfilled with a dry, inert gas selected to reduce convective heat load on coolers and ensure moisture and/or contaminant free operation. Standard packages are generally provided with sapphire windows but can be supplied with antireflection (AR) coated silicon or germanium windows and/or customer specified spectral filters. Detectors and arrays are also installed and tested in numerous custom designed and customer specified packages.
