According to the principle of infrared, to measure the temperature or image of objects behind glass or observation window glass, a short wave infrared detector with a size less than 3 microns is required.

DIAS Infrared, a German company, has developed and produced four types of shortwave infrared thermal imagers (infrared thermal imagers that penetrate glass for temperature measurement and imaging), including those from the pastPYROVIEW 640N compact+ ， A total of 5 types have been developedShort wave infrared thermal imager:
