Thorlabs stocks a wide selection of discrete photodiodes and calibrated photodiodes. These include Indium Gallium Arsenide (InGaAs), Gallium Phosphide (GaP), Silicon (Si), and Germanium (Ge) photodiodes, as well as Quadrant and Dual-Band photodiodes. The FGA20 provides high responsivity from 1200-2600 nm, allowing detection of wavelengths beyond the normal 1800 nm range of typical InGaAs photodiodes. In addition, we have a large variety of sockets available for all of our photodiodes.

The DSD2 is a single package that contains a silicon sensor and an InGaAs sensor stacked on top of each other. The package has four pins, two for each sensor. The combination of two sensors in one package provides a very wide spectral response detector that is ideal for broadband applications like remote temperature measurements where an extremely wide wavelength range needs to be monitored
