French term or phrase: doigt froid
Le refroidissement des capteurs thermiques à 77 °K (environ -196 °C), spécialement pour les capteurs sensibles dans la gamme de longueurs d’onde de 3-5 microns, est une condition incontournable de leur sensibilité, avec un rapport signal/bruit convenable. XXXXX produit en série les refroidisseurs Cryo 300/400 à cycle de Stirling, qui trouvent place aussi bien dans les imageurs thermiques portables (jumelles etc.) que dans les caméras à matrices de détecteurs, que les applications soient terrestres, navales ou aériennes, ou même dans des applications spatiales de détection infrarouge.

Capacité de refroidissement : 400 mW (pour 77 °K et 23 °C)
Temps de refroidissement : 3 minutes (entre 25 °C et 77 °K)
Diamètre du "doigt froid" : 6,9 mm
Stabilité de température du doigt froid : 0,05 °K
