Optical Power Monitor
1 General Information
The Thorlabs Optical Power Monitor (OPM) is a graphical user interface (GUI) designed for the
straightforward use of Thorlabs' power meters. The OPM monitors and saves power meter
measurements and features aninterface for data viewing and analysis. A variety of settings for the
connected devices, the display, and the measurement canbe easilyconfigured.
To control complex setups, the OPM can monitor up to 8 Thorlabs sensors on Thorlabs power
meters connected inparallel via USB or Bluetoothalso onyour tablet computer.
The OPM software provides continuous data logging, also for long-term measurements. Short-term
measurements are monitored and recorded bythe software witha highresolution.
The user can switch between displayed parameters and connected sensors at any time during an
active measurement or use the simulated analog needle view for assistance during tuning.
Log files saved by the OPM or data saved by a PM400 or PM5020 power meter can be loaded
into the OPM Data Viewer for viewing or analysis. Additionally, the OPM provides statistics
parameters to evaluate the results.
The displaylanguage canbe setto English, German, or Chinese.
Beyond these capabilities, the OPM provides a user-friendly design with reduced overall
brightness for comfortable work indark environments and highcontrast and minimized use of color
coding for operabilitywith laser safetyglasses.
The OPM supports the following Thorlabs devices and appropriate sensors and can administer
them inparallel.
