400mW RS046 Integral Rotary Stirling Cryocooler for Cooled Infrared Detectors

RS046 is a member 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 cooled infrared detectors.

With compact mechanical structure, and advanced c-rings sealing, RS046 detector dewar cooler (ddc) was specially developed to fit the applications where low input power, volume and weight are the most important parameters.

Global Sensor Technology is a supplier of cooled uncooled infrared detectors and infrared thermal imaging modules. We have more than 10 years of experience about infrared thermal imaging applications and a set of mature solutions available for customers. At the same time, we also have professional after-sales service team to provide you with professional reply.

1.What is infrared thermal imaging?

In nature, all objects whose temperature is higher than absolute zero (- 273 ℃) can radiate infrared rays. By using the infrared camera detector to measure the infrared radiation temperature difference between the target itself and the background, you can get different infrared images, which are also called thermal images.

2. How do infrared detectors work?

Infrared radiation that emitted by target enters the sensing range of the thermal detector, then the infrared detector converts the radiation signal of different intensity into the corresponding electrical signal, and then through amplification and video processing, forms the infrared image that can be observed by the naked eyes.

3.What are the advantages of cooled infrared detectors?

The cooled infrared focal plane detector operates at a low temperature which is provided by a detector dewar cooler (ddc). It has high sensitivity and can distinguish more subtle temperature difference than uncooled infrared detector. It can detect, identify and recognize objects at a very long range which is more than ten kilometers away. The structure of cooled detector is very complex which results in a relatively high cost than uncooled detector.
