Air-Cooled Thermopile Sensor, with Position Sensing, 45W

Manufacturer's part number :


Manufacturer Coherent


Description :

The LM-45 HTD position sensing air-cooled thermopile display the position of the incident beam on the sensor disk, in addition to measuring laser power when used with the Ultima LabMaster 2Ch, LaserPad and FieldMaster-GS meters. This information allows the user to safely and precisely align the sensor and the beam being measured. This is particularly useful for non-visible beams.
