Product Description

The 70K Cryocooler for cooling space telescopes is a critical technology designed to maintain the optimal operating temperatures required for sensitive infrared observations. These cryocoolers play a pivotal role in suppressing the infrared background "noise" and ensuring the detectors within scientific instruments function correctly by converting infrared light signals into electrical signals for processing into images . Product Description: A 70K Cryocooler is engineered to provide active cooling for space telescopes, particularly for instruments that require temperatures below the range achievable through passive means alone. The James Webb Space Telescope (JWST), for instance, utilizes a cryocooler dedicated to cooling its Mid-infrared Instrument (MIRI) detectors to less than 7 Kelvin, which is necessary for operating properly and suppressing random "noise" electrons . This cryocooler is advanced in two ways: it uses three stages of pulse-tube cooling compared to the traditional two stages, and it features a separation between the precooler and the JT cooling hardware, which is typically not more than several centimeters . Product Advantages: 1. Low Vibration: One of the most challenging requirements for a space telescope cryocooler is to operate with low vibration to prevent jitter and resultant blurred images. The pulse tube cooling in the precooler and the Joule-Thomson effect cooling in the cryocooler have no moving parts, and the only moving parts are the two 2-cylinder horizontally opposed piston pumps. These are finely balanced and tuned to minimize vibration, ensuring stable and clear imaging . 2. Extended Life Span: Unlike open systems that consume coolant, the cryocooler for space telescopes is a closed system, meaning its life is not limited by the consumption of coolant but by the wear of its moving parts or the longevity of its electronics. This feature ensures that the cryocooler can operate for many years, providing reliable cooling for the telescope's mission .
