USB-enabled Low Power Thermopile Sensor, 1W, 5µW NEP, 19 mm aperture

Manufacturer's part number :


Manufacturer Coherent


Description :

The PowerMax-USB PS19 model sensor is thermally stabilized, amplified thermopile power sensor with a broad spectral response, high sensitivity, and a large active area. This PowerMax-USB PS19 sensor is ideal for measuring laser diodes, HeNe and HeCd lasers, and small ion lasers. The PS10 model includes a light tube mounted to the front of the housing, which minimizes the effects of background radiation. The light tube can be removed and replaced by FC or SMA fiber connectors. The new PowerMax-USB PS19 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.
