Lightweight Integral Rotary Stirling Cryocooler 750mW for Cooled Infrared Detectors

Lightweight Integral Rotary Stirling Cryocooler 750mW For Cooled Infrared Detectors

RS079 is one of the integral rotary stirling cryocooler series developed by SensorMicro. 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.

We are a supplier of thermal infrared detectors and infrared camera module. After years of industrial application experience, we are capable to provide professional, efficient and convenient solutions for customers in all industries with its core technology of independent R&D infrared detector.

1. What is a cryocooler used for?
Cryocoolers are machines that keep sensors extremely cold so that thermal images can be taken on long-term missions. In many high-end applications, the sensors that capture images require extremely low temperatures.

2. What are the main factors to measure the quality of Cryocooler?
Long battery life and reliable operation are main factors to measure the quality of a cryocooler. Our cryocooler has a wide operating temperature range and excellent reliability. Its MTTF (Mean Time to Failures) has reached to 10,000 hours, which meets 24*7 boot operation requirements.

3. What is MTTF?
MTTF (Mean Time to Failure) measures a part’s reliability. It shows you how long on average a part lasts before it breaks and you have to replace it. On a basic level, it tells you about the quality of the parts you’re buying. The longer they last, the more value you’re getting from them.
