PM5020 Dual-Channel Benchtop Power and Energy Meter Chapter 2 General Information
The PM5020 power meter can be remote controlled via three different interfaces: the high-speed USB in-
terface, the built in Ethernet, or the serial RS232 interface.
The Thorlabs Optical Power Meter (OPM) Software fully supports the PM5020 power meter. The software
can handle multiple Thorlabs power meters simultaneously and additionally contains features like the
“user calibration wizard” or the “firmware update tool”.
The PM5020 power meter remote operation can be integrated into custom made systems with the help of
the provided SCPI commands and drivers. For PM5020 drivers, please either use NI-Visa drivers possibly
already installed on the PC, or use the Thorlabs TLP drivers which are installed with the Optical Power
Monitor (OPM) software. The Thorlabs TLP drivers are compatible with all other Thorlabs power meter
drivers. Please see the manual for OPM for more information.
In addition, the PM5020 power meter has a built in webserver that enables monitoring of the most inter-
esting functions within a local area network.
