Laser Energy Sensors
Ophir photodiode laser energy sensors are able to measure low energy pulses down to 10pJ at frequencies up to 20 kHz. Silicon photodiodes for the UV and visible spectrum and Germanium photodiodes for infrared.
Pyroelectric sensors for measuring repetitively pulsed energy at up to 25 kHz. Ophir pyroelectric detectors have unique and proprietary circuitry that allow them to measure long pulses as well as short pulses and work at a high duty cycle, i.e. where the pulse width is as much as 30% of the total cycle time.
