Photodiode Sensors
Ophir's Photodiode PD-300 series sensors offer spectral coverage from 200nm – 1800nm, and automatic background subtraction so the measurement is not sensitive to room light.
All models have wavelength calibration built into the system.
Ophir pyroelectric laser energy sensors use innovative, patented technology which facilitates accurate and repeatable measurements over an extensive range of conditions.
Thermal (Thermopile) Sensors - Low Powers to 50W
Ophir has the widest selection of laser power sensors for low average powers in the industry. From the popular 3A series that can reliably measure down to tens of micro watts and micro joules to the L50A for up to 50W continuous
Ophir has a wide range of thermal laser measurement sensors. Included are the exclusive LP1 coating with the highest damage thresholds available for long pulses and continuous radiation. There are sensors with apertures up to 65mm diameter.
Ophir's high power sensors are the most reliable and durable. Included are the exclusive 10K-W sensor withstanding power densities 10KW/cm² at 10KW power level, and the FL500A fan cooled sensor for up to 500 Watts.
The low cost Comet power probes are perfect for laser job shops. They give simple
and accurate power measurements up to 10KW and 10KW/cm2
Ophir has special photodiode products for special applications: the low cost PD200 sensor and power meter for those who only want to measure one or two wavelengths. The FPS-10 to measure temporal pulse shape and the WaveStar spectrum analyzer.
Especially for high rep rate, high average power lasers.
Ophir offers several integrating sphere smart sensors for measurement of divergent beams and diode lasers 1µW-100W
