PowerMax-USB/RS Sensors

Laser power measurement with state-of-the-art microelectronics miniaturization techniques, integrated in an entire instrument within a USB 2.0 or RS-232 cable connector.

Key Features:

  • PowerMax-RS provides RS-232 connectivity. Power input provided via +5 VDC 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 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.

Overview

The new PowerMax-USB/RS sensors are 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.

Benefits

These new PowerMax products will benefit a wide range of users. These include OEMs 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

PowerMax Software

Coherent’s PowerMax PC applications software provides a virtual instrument interface for these sensors that enables the operator to take laser power readings, log data and compute measurement statistics. Users can also write their own software using host interface commands that control all aspects of power meter operation.

Plug-and-play application software is supplied standard and includes the following software features:
Compatible with Microsoft Windows 7, 8, and 10, 32-bit and 64-bit operating systems.

  • Trending
  • Statistics (mean, minimum, maximum, and standard deviation) and log batch to file
  • Tuning
  • Display beam position on position-sensing thermopiles and log results to file
  • Histogram
  • Operate multiple devices simultaneously
  • Perform synchronized ratiometery (A/B analysis). Trend and log results to file
  • For LaserPAD and SSIM customers, the host command set includes drop-in compatibility
