Optris CT XL 3M infrared pyrometer for laser applications

Optris CT XL 3M infrared temperature sensor for laser welding applications

 

Optris CT XL 3MH Infrared Pyrometer

The Optris CT XL 3MH has been designed for use in applications where lasers are used. This may be for laser welding, machining or brazing. The sensor operates in the 2.3 µm part of the infrared spectrum making it ideal for high temperatures of metals. A filter is fitted to prevent damage from exposure to lasers.

Selectable optics allow you to choose the most appropriate spot size for your application with a smallest spot of 0.5mm possible. The sensor also has a very fast response time of just 1ms. It is also easy to connect our innovative USB interface which allows simple configuration and on screen measurement with the included Compact Connect Windows software.
Calibration as well as a full range of accessories are available for the Optris High Performance infrared pyrometers.

Features

New infrared thermometer for laser material processing, laser welding and laser soldering
Special blocking filter against laser radiation of most of all diode lasers and solid state lasers (VIS to 1800 nm and 10.6 μm)
Far focus version for use with laser collimator optics
Usable up to 85°C ambient temperature without cooling
Short wave length range of 2.3 μm to reduce error of reading with measurements on materials with unknown emissivity
