RS046H Split Integrated Dewar Cooler Assembly
RS046H Cryo Cooler
RS046H 400mW Split Rotary Stirling Cryocooler for Cooled Infrared Detectors
Product Description
RS046H is a split version of the RS046 rotary stirling cooler developed by SensorMicro. With the same compressor structure as RS046, the split format RS046H features an even more compact size.
The cold finger in RS046H dewar cooler maintains the same diameter as the RS046 cooler but with a shorter length. The split design separating the compressor and cold finger provides flexibility for specialized infrared system designs. Additionally, separating the cooled detector from the vibration source makes RS046H optimal for applications requiring minimal vibration and specific environmental conditions.
Due to its lightweight construction, miniaturization, and low power consumption, the RS046H cryo cooler integrates easily into various terminal products, significantly reducing costs while meeting diverse customer customization requirements.

Frequently Asked Questions
What is infrared thermal imaging?
In nature, all objects with temperatures above absolute zero (-273℃) radiate infrared rays. Using infrared camera detectors to measure temperature differences between targets and backgrounds produces different infrared images, also known as thermal images.
How do infrared detectors work?
Infrared radiation emitted by targets enters the thermal detector's sensing range. The infrared detector converts varying radiation intensities into corresponding electrical signals, which are then amplified and processed to form infrared images visible to the naked eye.
What are the advantages of cooled infrared detectors?
Cooled infrared focal plane detectors operate at low temperatures provided by detector dewar coolers (DDC). They offer high sensitivity, distinguishing more subtle temperature differences than uncooled detectors, and can detect, identify, and recognize objects over distances exceeding ten kilometers. While their complex structure results in higher costs than uncooled detectors, their performance advantages are significant for demanding applications.
