High Peak Power 100 W Thermopile Sensor with 120 mm Aperture
High Peak Power 100 W Thermopile Sensor with 120 mm Aperture
The L100(500)A-PF-120 thermopile sensor is a convection or conduction cooled laser power and energy thermal sensor with a very large 120 mm aperture. It can measure power optical power from 1 W to 500 W and energy from 6 J to 6000 J. It has the PF volume absorber and covers the spectral range from 0.15 to 20 µm.
- PF type 0.15-20 µm high peak power absorber
- 1000 mW to 100 W average power measurement
- 6 to 6000 J pulse energy measurement
- 500 W power measurement intermittently See All Features

Choosing a Thermal Sensor
In this short “Basics” video we review the use – and selection - of thermal sensors for measuring low, medium and high laser powers.
Sensors for Measuring Laser Power
In this short "Basics" video we review in general how one goes about measuring laser beam power, so that you'll have a clear understanding of what the different sensor types are, and when to use each type.
Understanding Peak Power vs. Average Power
A pulsed laser could have an average power of, say, 1 Watt, yet a peak power of 1 Megawatt – so when specifying it’s rather important to understand the difference. In this video you will learn what exactly these 2 concepts mean. You’ll also learn how to measure Peak Power, which can sometimes be tricky.
Effects of Incidence Angle on Measurements
In this video, you will learn to what degree a beam’s incidence angle matters, and for which sensor types this should be taken into account.
Thermal Sensor Calibration
As the spectral sensitivity of the absorber used for the power and energy measurement is not fully linear, Ophir sensors get a high precision calibration by default with more than one wavelength.
Each thermal sensor is calibrated independently of a particular Ophir power meter with its calibration information contained in the DB15 plug. When the sensor is connected to the meter, the meter reads and interprets this information to display a calibrated reading. Each power meter is calibrated independently and has the same sensitivity as an other meter within about 2 tenths of a percent.
Unless otherwise indicated, Ophir sensors and meters should be recalibrated within 18 months after initial purchase, and then once a year after that.
