RS046H Split Integrated Dewar Cooler Assembly

RS046H 400mW Split Rotary Stirling Cryocooler for Cooled Infrared Detectors

RS046H is a split version of RS046 rotary stirling cooler developed by SensorMicro. With the same compressor structure of RS046, the split format RS046H is even smaller in size.

The cold finger in RS046H dewar cooler has the same diameter as that in RS046 cooler but with shorter length. Benefit from the split design of the compressor and the cold finger, the infrared system with RS046H integrated is flexible in special design. What's more, the cooled detector itself is separated from the vibration source, which enables the RS046H optimal in application requiring better vibration and special conditions.

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.

The RS046H integrated dewar cooler assembly is used for provide cryogenic environment for the cooled infrared detectors.

SensorMicro was founded with a simple but powerful belief: Innovation should serve real-world needs.

SensorMicro exists to empower people and systems to see beyond the surface—into the patterns, the problems, and the possibilities that lie beneath.

By turning invisible heat into visible truth, we help industries make smarter decisions, protect what matters most, and navigate complexity with clarity.

Heeding to our insistence on being self-made and customer-first has become a sure recipe for SensorMicro's momentum. As our business spans much of the globe, we've charged ahead on all fronts—from security, firefighting, industrial inspection, medical care, and machine vision, to environmental monitoring and key aspects of carbon neutrality—helping partners unlock the full potential of intelligent infrared sensing, and connecting the dots of life.

We are more than an infrared technology company. We are a community of people committed to building a sustainable, ethical, and human-centered future. Every pixel of innovation we create is a promise — a promise to protect, to empower, and to serve.

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.
