These direct bandgap semiconductor devices have excellent speed of response and linearity. They are a little bit noisier than silicon detectors, due to the smaller band gap, and therefore we offer one with two-stage TE cooling for radiometric applications. The 1.3 µm and 1.55 µm wavelengths, lie within the 0.8 to 1.7 µm detection range. Transmission and loss measurements can be done most accurately with these extremely stable and sensitive detectors.
