USB-enabled Low Power Thermopile Sensor, 1W, 3µW NEP, Quartz filter, 19 mm aperture

Manufacturer's part number :


Manufacturer Coherent


Description :

Where optimum stability is required, specify the PowerMax-USB PS19Q, which include a wedged quartz window for applications from 0.3 to 2.1 μm. The quartz window more effectively eliminates thermal background radiation and the effects of air currents. The new PowerMax-USB PS19Q 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 or RS-232 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.
