Photodiode arrays

Sensors Unlimited

Sensors Unlimited will feature the addition to its line of InGaAs linear photodiode arrays, a new wavelength range of 0.7 to 1.45 m, at  SPIE Photonics West 2016 in San Francisco, 13-18 February.  The new version joins arrays with cut-off wavelengths of 1.7, 2.2 and 2.6 m (@ room temperature).

All versions exhibit reduced dark current and improved uniformity as a result of new equipment and processes at the Sensors' facility. Designers have the choice between two families of readout devices, the integrate-then-read LDB/LE or the integrate-while-read LC.

The LC version is the choice for fast line times, while also offering four programmable gain options. One of the gains provides the largest available full-well for absorbance spectroscopy.
