3 Description
The Thorlabs PMxxx Power Meter system is a flexible optical power measurement
system that easily expands as your measurement needs grow. The system is based
on a universal console which displays the measurement on a graphic LCD read-out
and is controlled by an easy-to-use keypad.
Thorlabs offers a wide range of interchangeable sensor heads to use with the PM100
console. Large area silicon and germanium semiconductor heads cover the range
from visible to mid IR with nW sensitivity. For higher power measurements, Thorlabs
offers a line of thermal sensors that will measure up to 30W with sophisticated
circuitry enabling fast measurement results.
Please refer to www.thorlabs.com for new sensors that will enhance the PM100
system.
Each sensor head includes a non-volatile memory chip, which stores the NIST-
traceable calibration of the sensor along with other relevant data such as model
number, serial number, wavelength range, etc. The console automatically recognizes
the attached sensor head during the operation and adjusts the system accordingly to
maintain NIST-traceable, reliable power measurements.
The LCD graphics screen displays the real time optical power in large, easy-to-read
digits supported by a fine resolution bar graph. An x-y plot mode provides an
oscilloscope-type display of the power reading. The analog needle display is ideal for
tuning laser systems or aligning fiber launch systems. For process monitoring, real
time statistics such as min/max/mean/std dev are accessible through the statistics
mode. The display includes a backlight for easy viewing in dim lightning conditions.
The console includes an RS-232 serial port for remote access to the power meter, as
well as a configurable analog output for externally monitoring the power reading.
The console is powered by a 3.6V, 1500mAh nickel-metal-hybrid (NiMH) battery pack
for long life operation and fast recharging times. The included external power supply
is provided to recharge the battery pack as well as to operate the unit independent
from the battery pack.
