RS079 750mW Integral Rotary Stirling Cryocooler for Cooled Infrared Detectors
RS079 is one of the integral rotary stirling cryocooler series developed by Global Sensor Technology (GST). It provides a miniature closed cycle cooling system to ensure a cryogenic working environment for the normal operation of stirling cooled detectors.
Its motor windings are separated from the working gas to prevent contamination. High wear-resisting coating and clean room assembly are applied to prolong the lifetime and high reliability. For compactness, the electronic drive is built-in. An onboard temperature sensor offers stand-by, remote shutdown and over-temperature protection options. With high performance, RS079 dewar cooler assembly is designed to meet the demand for high cooling power of the large FPA formats.
Due to its lightweight, miniaturization and low power consumption, it is easier for the cryo cooler to be integrated into various terminal products, which can greatly reduce the cost and meet different customized needs of customers.

1.What is the difference between low light, active IR and thermal imaging?
Low light needs natural light and transforms weak natural light image into enhanced electronic image through image intensifier;
Active IR actively emits infrared light and uses infrared beam reflected by the target. It has very poor concealment;
Thermal imaging doesn’t need any light and is a passive infrared night vision that detects infrared radiation difference between targets and scene or different parts of an object. not be affected by the changes of the surrounding lighting conditions, during night or even in fog, rain and other harsh environments.
2. Can you block thermal imaging?
In most cases, you cannot. But infrared rays can't penetrate walls, and also the glass can block IR. So, if you don’t want to be detected, you can conceal behind glass or walls to block the thermal imaging.
