1 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. Its
high repetition rate with up to 80kHz 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 in-
terfaces for instrument control and output:
· PM103: USB port and DA-15 connector
· PM103A: USB port (Input and Output) and SMA analog interface (Output only)
· PM103U: USB port only
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 facilita-
ted via the USB port. The PM103 can alternatively use the DA-15 interface for instrument con-
trol and to connect a power supply. 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 of-
fers the Optical Power Monitor (OPM) software. Instead of the OPM software, 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, as well as
provide a supplied control and analysis software and the option to use custom made software.
Further, the PM103 can even be controlled via an external micro-controller, supplied by the
customer. 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 manufactu-
ring, quality control, quality assurance, and R&D for stationary and field use.
