The Trius SX35 and SX36 cameras are the largest in the SX line of Truesense CCD based imagers. We have used an improved two stage Peltier cooler for efficient CCD cooling, and a high-speed USB2 interface circuit for a short download time. The fast download minimises the visibility of bias frame artefacts, such as hot columns and the top to bottom gradient that is commonly seen on such chips. The camera shown on this page is the SX36, as both versions have a closely similar appearance.
