This series is easy to use, no cooling or heatsink needed. The devices are optimized for the maximum performance at λopt. Cut-on wavelength can be optimized upon request. Reverse bias may significantly increase speed of response and dynamic range. It results also in improved performance at high frequencies, but 1/f noise that appears in biased devices may reduce performance at low frequencies. Highest performance and stability are achieved by application of variable gap HgCdTe semiconductor, optimized doping and sophisticated surface processing. Standard detectors are available in TO39 or BNC packages without windows. Various windows, other packages and connectors are available upon request.
