Laser Components IG, Inc.
Pyroelectric detectors are thermal detectors; i.e. they create an electric signal due to temperature changes in the chip. This temperature change is caused by absorption of light. We do use LiTaO3 and DLaTGS as pyroelectric materials. Basically such detectors cover the whole spectra. However, they are mainly used for mid-wave and long-wave infrared detection (MWIR and LWIR). In addition, the usage in the THz region seems to become more popular these days.

mks Ophir
Pyroelectric sensors for measuring repetitively pulsed energy at up to 25 kHz. These sensors use a pyroelectric crystal that generates an electric charge proportional to the heat absorbed. The response time of the pyroelectric sensor depends on the time it takes for the heat to enter the crystal and heat it up. For metallic type pyro detectors, this time is tens of μs and thus the metallic type can run at a high repetition rate. For the BF and BB type, the response time is milliseconds with a correspondingly lower repetition rate. 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.

InfraTec GmbH
Due to their spectral properties and robustness, pyroelectric detectors have proven themselves for many years in numerous applications in gas analysis, flame detection and spectroscopy. They enable the tuning of the optical filter over a defined spectral range by simply adjusting the control voltage. Instead of mounting filters to inspect specific areas of interest as is conventionally common, the detector with tunable Fabry-Pérot filters (FPF) can be used to monitor a broad spectral region continuously.

PM 200 -
Scitec Instruments Ltd
In the past laser energy meters often required a whole selection of pyroelectric detectors for measuring different energies. From this point of view the PM 200 is a very modest instrument. A single detector enables monitoring of energies from the detection limit at 3 ?J up to highest energies of 200 mJ. The active sensor area with an aperture diameter of 34 mm ensures simple and reliable alignment for the detection of large beam profiles.?
