Coherent LM-2 VIS Semiconductor Power Sensor Description：

Datasheet

LM-2 high-sensitivity optical sensors are ideal for measurement in the nW to low mW level. An optional 1000:1 attenuator is available (PN 1098318) to support operation up to 5 Watts. SMA-type (PN 1098589) and FC/PC-type (PN 1098339) fiber optic adapters are available.

The sensor is terminated in a SmartSensor DB25 cable and is directly compatible with LabMax meters. For compatibility with other catalog meters choose the OP-2 VIS model (PN 1098313).

Low power silicon semiconductor power sensor for measuring CW lasers between 10 nW and 30 mW.
