SBIG STF-8050

The SBIG STF-8050 camera comes in monochrome (STF-8050M) and two color models. The color models are available with either the standard Bayer Color FIlter Pattern (STF-8050C) or the higher sensitivity TRUESENSE Sparse Color Filter Pattern (STF-8050SC). The KAI-08050 Image Sensor is an 8-megapixel CCD in a 4/3″ (22 mm diagonal) optical format. Based on the TRUESENSE 5.5 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-8050 has been optimized for fast full frame download and maximum cooling in an STF sized package. A high resolution 8.3 megapixel 16-bit frame will download in about 1/2 second using the dual channel readout mode. Even at this rapid download rate, the read noise remains exceptionally low, about 9e-. The tables below show download times and frame rates for the STF-8050 camera measured using our high speed drivers:

• STF-8050 Download time in seconds for single frame

• STF-8050 Frames per second saved to disk using high speed drivers

To reduce the necessity for dark frames, the STF-8050 is designed with exceptionally strong cooling, capable of a cooling delta greater than -50 degrees C. This means that the camera at room temperature can cool enough to reduce the dark current to 1/100th of an electron per pixel per second, or less.
