Coherent PowerMax-USB/RS Sensors

The new PowerMax-USB/RS sensors are the world's first laser power sensors that utilise state-of-the-art microelectronics miniaturisation techniques, and integrate an entire instrument within a USB2.0 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 saving in cost and space but with no reduction whatsoever in performance.

PowerMax-USB contains a USB2.0 connector, and the PowerMax-RS contains an RS-232 connector.

• PowerMax-USB provides direct USB2.0 connection to PC, power provided via USB connection
• PowerMax-RS provides RS-232 connectivity, power input provided via +5VDC input from external power supply or through pin 1 on RS-232 connector
• Instrumentation platform is compatible with thermopiles and optical sensors and can be adapted to most power sensors that Coherent Inc manufactures
• Displays beam position with position-sensing quadrant thermopiles (with LM-model sensors like LM-10)
• High resolution 24-bit A/D converter supports four digits of resolution and measurement accuracy equivalent to that found in Coherent's LabMax meters
• Spectral compensation is unique to each device for improved accuracy
• Long-pulse joules capability with thermopile sensors
• NIST traceable measurements

These new PowerMax sensors will benefit a wide range of users. These include OEM's who want to embed power measurement electronics within their own instrumentation, field service engineers who already carry a laptop computer, and operators of computer controlled laser burn-in racks and long-term reliability test benches. In addition, PowerMax-USB/RS sensors are useful for general laboratory applications in which experimental data acquisition is performed from a central PC.
