Infrared thermometer optris CT XL 3M for temperature measurement of laser applications

Due to its integrated blocking filter against laser radiation the infrared thermometer optris CT XL 3M is perfectly suited for temperature measurement of laser processing applications. Additionally, it is equipped with a far focus version optimally combinable with laser collimator optics.

Furthermore, the IR thermometer optris CT XL 3M enables you to measure smallest objects and, due to its quick response times, monitor very fast processes.
