For Spectroscopy and Interferometry Applications
PRINCETON, N.J., May 14, 2008 -- Sensors Unlimited Inc. said its new LC series shortwave infrared (SWIR) linear photodiode array extends beyond other near-infrared (NIR) linear arrays to deliver high sensitivity for imaging applications from .9 to 2.6 µm.

The device offers instrument designers several advantages: no moving parts, easy integration into existing systems, fast signal readout, and real-time measurement results for an attractive alternative to FTIR-NIR (Fourier transform infrared-NIR) interferometry, said SUI, which is part of Goodrich Corp.

The new InGaAs linear photodiodes with the extended 2.6-µm wavelength array also offer wider spectral range and improved functionality over FTIR-NIR instrumentation.

Developed specifically for broad-wavelength-range, multichannel spectrometer designs, the SU256LSC-2.6T2 detector array features 256 elements of extended response InGaAs material. The LC InGaAs photodiode array is vibration-resistant, easy to use, and has a large active area, 50 x 250-µm pixel size.

LC package design includes a two-stage thermoelectric cooler and thermally-optimized materials for multichannel spectrometers that require high sensitivity, low power consumption, and long-term stability.
