Datasheet 1 Datasheet 2 User's Manual

This PowerMax-USB LM-3 sensor is terminated in a USB cable that interfaces directly to a PC. A DB25 model (PN 1098328) is available.

SMA fiber adapter (PN 1098589) and FC/PC fiber adapter (PN 1098339) accessories are available.

These unique position sensing thermopiles display the position of the incident beam on the sensor disk, in addition to measuring power. 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.
