Coherent® PowerMAX-USB Laser Power Meters

  • Plug and Play USB 2.0 Interface
  • Available with High Sensitivity Photodiode or Thermopile Sensor
  • Displays Beam Position with Position Sensing Quadrant Thermopiles

The Coherent® PowerMax-USB sensors feature a plug and play USB 2.0 interface turning your PC into a laser power meter system without the need for additional electronic instrumentation. The platform provides a less costly laser power measurement system than a traditional meter and sensor configuration purchased separately. For customers who recalibrate annually the overall cost of ownership is cut in half because only one recalibration is required. These power meters are available with either a photodiode or thermopile sensor with high resolution 24-bit A/D converter.

Photodiode sensors offer very high sensitivity and are suitable for low power lasers. The included neutral density filter allows the sensor to be used with hundreds of milliwatts without saturation. Thermopile sensors operate in a wide range of input powers making them a great all purpose technology for many lasers. Long pulse joule mode allows for easy measurement of long pulses greater than 1ms. Plug and play application software and Labview drivers are included with each laser power meter for easy system integration. Customers can also utilize the PC’s command prompt to send commands to the software via the USB 2.0 interface for easy programming with any Windows operating system. The software allows users to operate multiple devices simultaneously and performs radiometric analysis, trending, statistics, and data logging. In addition, these power meters are suitable for applications in which the sensor is dedicated to, or embedded in, a larger system.
