The XLIN 1.7/2.2/2.5 series InGaAs linear photodiode arrays from XenICs are for IR detection. The XLIN comes with pixel counts of 128, 256 and 512. It offers a wavelength response of up to 2.5 μm and a readout rate of more than 9000 lines per second. The XLIN 1.7 is suited for 0.9 to 1.7-μm wavelengths, the 2.2 operates at up to 2.2 μm, and the 2.5 operates at 2.5 μm. The arrays are hermetically sealed in a standard flat-bottom package with a coated antireflection window and extending fixation flanges.
