Coherent LM-150 LS Laser Power Sensor Description:

Datasheet

This compact LM-150 LS sensor is designed for intermittent use at higher powers up to 150W (for two minutes) without water or fan cooling. It is terminated in a SmartSensor DB25 cable and is directly compatible with LabMax-TOP, LabMax-TO and LabMax-Pro SSIM meters. A Thermal SmartSensor Adapter PN 1056827 is required to use this sensor with FieldMate, FieldMaxII-TOP and FieldMaxII-TO meters.

A USB-direct (PN 1275678) model is available.

This LM-150 LS version has a rectangular form factor, whereas the LM-150 FS (PN 1098394) is round.

SMA fiber adapter (PN 1098589) and FC/PC fiber adapter (PN 1098339) accessories are available when used with 1.035-40M Adapter Ring (PN 33-9432-000).

These unique position sensing thermopiles display the position of the incident beam on the sensor disk, in addition to measuring power when used with the LabMax and LabMax-Pro 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.

Compact convectively cooled thermopile for measuring pulsed & CW lasers intermittently up to 150W with beam position measurement:

2 minutes at 150W

5 minutes at 100W

20 minutes at 40W
