Laser Energy Sensors

Ophir has two types of energy sensors, pyroelectric and photodiode. Pyroelectric sensors are for measuring repetitive pulse energies and average powers at pulse rates up to 25000 pulses per second and pulse widths up to 20 ms. Photodiode energy sensors are for very low energy pulsed lasers, as low as 200 pJ. Note that single shot energy with pulse rates less than one pulse every 5 s or so can be measured with thermal sensors. Ophir's sensor finder allows you to easily find the sensor that best suits your application

Laser Pyroelectric Energy Sensors

Pyroelectric Laser Energy Sensors – 0.05µJ to 10J

Ophir pyroelectric laser joule meters use innovative, patented technology which facilitates accurate and repeatable laser measurements of pulses over an extensive range of conditions including long pulses to 20ms. Ophir’s pyroelectric detectors have metallic coating which allows for high repetition rates of upto 25KHz.
