PM103x Optical Power Meter Interfaces Chapter 2 General Information
Chapter 2 General Information
The PM103x Optical Power and Energy Meter interfaces measure the optical power of laser light or
other monochromatic or near monochromatic light detected by a connected sensor. Their high
repetition rate up to 80 kHz supports even fast pyroelectric sensors. The PM103x power meter
interfaces are compatible with all Thorlabs “C-Series” Photodiodes, Pyroelectric sensors, and
respective custom sensors.
To flexibly integrate the PM103x into a setup, the PM103x models offer different electronic
interfaces for instrument control and output:
·PM103: USB port, Dual I/O port, and DA-15connector
·PM103A: USB port and SMA analog interface (Output only)
·PM103U: USB port only
·PM103E: Ethernet Port, Phoenix DMC Connector, Dual I/O port
The USB port features a fixture for secure connection of the cable to the housing.
For the PM103U and PM103A power meters, instrument control, and power supply are facilitated via
the USB port. The PM103 can alternatively use the DA-15 interface for instrument control and to
connect a power supply. Furthermore, the PM103 can be controlled via an external micro-controller,
supplied by the customer.
The PM103E can use the ethernet cable for power supply, if the network supplies Power over Ethernet
(PoE). Alternatively the PM103E can be powered via its Phoenix DMC Connector. For more information
on the special features of the PM103x models, please see the table PM103x Model Comparison
below.
For instrument control and data analysis through a connected PC, tablet or laptop, Thorlabs offers the
Optical Power Monitor (OPM) software. Instead of the OPMsoftware, the user can write custom made
software. For this, information on driver and SCPI commands are provided in the manual
WriteYourOwnApplication (WYOA) for the PM103x.
In summary, the PM103x models give the customer the choice of different interfaces, provide a
supplied control and analysis software, and have the option to use custom made software. These
features allow for maximum flexibility to integrate the instrument in test and measurement systems
and a wide range of industrial and scientific applications in manufacturing, quality control, quality
assurance, and R&Dfor stationary and field use.
The PM103x offers the customer to implement a large number of powermeters parallel and at the same
time into their application.
