USB-enabled OEM Thermopile Sensor, 20W, with Position Sensing

Manufacturer's part number :


Manufacturer Coherent


Description :

The LM-20 is designed for embedded use and must be mounted on a heat sink. The new PowerMax-USB LM-20 sensor is the world's first laser power sensors that utilize state-of-the-art microelectronics miniaturization techniques, and integrate an entire instrument within a USB 2.0 cable connector. Specifically, PowerMax-USB/RS sensors contain all the signal processing and power measurement electronics normally found in a LabMax meter, and provide the capability to connect directly to a PC with plug-and-play functionality. Ideally suited for low and high volume embedded sensor applications, Coherent's new family of sensors eliminates the need for a separate meter box, thus delivering a significant savings in cost and space but with no reduction whatsoever in performance.
