Working principle of infrared thermometer for temperature measurement of German OPTRIS laser products
Thanks to its integrated blocking filter for laser radiation, the infrared thermometer optris CT XL 3M is ideally suited for temperature measurement of laser processed products. Additionally, this infrared thermometer is available in a far-focus version that can be combined with laser collimator optics.
In addition, the optris CT XL 3M infrared thermometer can measure very small objects, and due to its fast response time, this thermometer detects faster.
