The ISC0402 is the latest large-format 20-micron pixel ROIC design. Compatible with P-on-N detectors like InSb, QWIP, InGaAs, and MCT, this is a large-format 640 .× 512 array. It offers the same advanced features as our standard designs including windowing, image transposition, adjustable gain, interlaced/non-interlaced readout, power adjustment, and multiple output channels. Two versions of the design are available with different size integration capacitors 3.5e6 for the smaller well and >6e6 electrons for the large well version.
