CCD and InGaAs arrays

Pacer supplies CCD and InGaAs arrays from PerkinElmer and Judson Technologies.

PerkinElmer Optoelectronics supplies state of the art linear, TDI, and area image sensors offered as both bare devices or as the heart of uniquely designed cameras. The range includes CCD cooled area arrays, CCD linear arrays, CMOS linear arrays and TDI imagers. 

Judson Technologies offers multiplexed InGaAs linear arrays. The J22M Series are high performance InGaAs linear arrays designed for telecom applications in the S, C and L band.  The J23M Series are InGaAs linear arrays with extended NIR cutoffs at 1.9µm, 2.2µm, 2.4µm and 2.6µm for applications in spectroscopy and thermal imaging.

The J22M and J23M arrays are coupled to buffered CMOS multiplexers and are offered in sizes of 128 and 256 elements with 50µm channel spacing and 500µm pixel height.  The integrating amplifier maintains zero voltage bias across each InGaAs photodiode minimizing dark current and low frequency noise.  With high input impedance CMOS, charge coupled transimpedance amplifier and four computer selectable well capacitors, our MUX design offers low noise and a wide dynamic range.
