The STF-4070 camera comes in monochrome (STF-4070M) and two color models. The color models are available with either the standard Bayer Color FIlter Pattern (STF-4070C) or the higher sensitivity TRUESENSE Sparse Color Filter Pattern (STF-4070SC). The KAI-04070 Image Sensor is a 4-megapixel CCD in a 4/3″ (21.4 mm diagonal) optical format. Based on the TRUESENSE 7.4 micron Interline Transfer CCD Platform, the sensor features broad dynamic range, excellent imaging performance, and a flexible readout architecture. The TRUESENSE Sparse Color Filter Pattern provides a 2x improvement in light sensitivity compared to a standard color Bayer part.

In addition to the new color technology, the STF-4070 has been optimized for fast full frame download and maximum cooling in an STF sized package. A high resolution 4 megapixel 16-bit frame will download in about 1/4 second using the dual channel readout mode. Even at this rapid download rate, the read noise remains exceptionally low, about 9e-.
