Tiny coolers for infrared detectors [ES2016D4]

16 June 2016

One of a small number of world specialists in cryogenic coolers is Slovenia-based Le-tehnika (Hall 6, Stand J138). These advanced miniature cooler units are designed to cool infrared detectors for surveillance, defence, medical and special equipment.

A typical example is the actively controlled Joule-Thompson miniature cooler (ACC), which was developed together with Diehl BGT Defence for cooling the IR sensor of the German firm’s IRIS-T missile. According to Drago Lemut, Le-tehnik’s managing director, the main advantage of the ACC is reliability and its low sensitivity to impurities, compared with bellow-type JT coolers. “We are flexible in production, meaning we can quickly deliver samples or small quantities for evaluation,” Lemut explained.

In addition to the ACC, Le-tehnik also designs and manufactures a wide range of other cryocoolers.
