Measure Optical Power and Energy
Thorlabs’ extensive line of optical power and energy meters includes power meter
consoles, a large selection of sensor heads, and complete all-in-one power meters.
When combined with our sensor heads that use C-series connectors, our consoles
can provide calibrated (NIST-traceable) optical power and energy measurements
from the UV to the IR. C-series sensors are available in photodiode, thermal, or
pyroelectric formats enclosed in a range of housings, including ultra-slim sensor
heads for measurements in tight spaces and microscope-slide sensor heads for use
with imaging systems.
We also offer three styles of complete power meters. Our wireless power meters
include a small OLED screen for local control and incorporate Bluetooth® technology
to support remote operation through free apps for Android™ or iOS®. Fiber power
meters feature a rugged design and an internal sensor for measurements in the lab
or the field, while compact USB power meters can be connected to the USB port of
any computer and controlled via Thorlabs’ Power Meter Software.
Optical Power and Energy Meter Consoles
Thorlabs’ Optical Power and Energy Meter Consoles are designed to display calibrated measurements when used with our
photodiode, thermal, or pyroelectric C-series sensors. They are available in a variety of formats from the PM100A analog
needle console to the PM400 digital touchscreen console.

The PM400 features advanced spectral correction capabilities that allow
the user to save and apply calibration and attenuation correction files. The
capacitive touchscreen enables fast access to measurement settings, while
the use of multi-touch technology allows data displays to be zoomed and

a. Select sensors are offered from stock in our Compact USB Power Meters. To order other sensor heads in this format, please contact [email protected].
b. Of the Photodiode Sensor. Actual response time will be limited by the update rate of the console.
c. Response time is limited by the sensor material. Thorlabs' thermal sensor and power meter consoles are designed so that the incident power can be determined after a
single sensor time constant, which results in a lower response time than other comparable thermal sensors.
d. With Intermittent Use (Maximum Exposure Time of 20 Minutes)
e. All pyroelectric sensors have a 20 ms thermal time constant, τ. This value indicates how long it takes the sensor to recover from a single pulse. To detect the correct
energy levels, pulses must be shorter than 0.1τ and the repetition rate of your source must be well below 1/τ.
