Cryogenic Cooler

Cryogenic coolers are devices used in night vision equipment to cool the infrared detectors. These coolers are part of the supply class Night Vision Equipment, which falls under the supply group Communication, Detection, And Coherent Radiation Equipment.

Night vision equipment allows users to see in low-light or dark conditions by detecting and amplifying the available light, including both emitted and reflected radiation. Infrared detectors are used to capture the infrared radiation emitted or reflected by objects in the environment. However, these detectors need to be cooled to very low temperatures to improve their sensitivity and reduce noise.

Cryogenic coolers, also known as cryocoolers, are used to achieve this cooling. They work by utilizing the principles of thermodynamics and cryogenics to lower the temperature of the infrared detectors. Cryocoolers can achieve temperatures as low as -200 degrees Celsius (-328 degrees Fahrenheit) or even lower, depending on the specific application.

By cooling the detectors, cryogenic coolers enhance the performance of night vision equipment, allowing for better image quality and increased detection range. They are essential components in various applications, including military night vision goggles, thermal imaging cameras, and surveillance systems.

In summary, cryogenic coolers are devices used in night vision equipment to cool the infrared detectors, enabling the detection of emitted and reflected radiation. They belong to the supply class Night Vision Equipment, which is part of the supply group Communication, Detection, And Coherent Radiation Equipment.
