A sensor, which is part of a line claimed to provide the industry's lowest measurable energy, longest measurable pulse width and highest accuracy, has been released by Ophir Photonics. Covering a wide range of wavelengths, from 0.19µm to 2.9nm, the F-PE80BF-DIF-C sensor is fan-cooled.

Very high energy/peak power lasers, including Nd:YAG and harmonics, can be measured using the device. Providing energy measurement down to 0.5mJ, the sensor measures pulses with average powers to 200W. According to the company, this is three times higher than other products on the market.

Damage thresholds to 50J/cm2 at 2ms, claimed to be the highest in the industry, are delivered by a BF coating and diffuser. Preventing false readings in noisy environments, the F-PE80BF-DIF-C sensor provide a user adjustable threshold. Repetition rates up to 25kHz and pulse widths up to 20ms are supported by the sensor.

The F-PE80BF-DIF-C is suitable for high power, short pulse YAG laser and harmonic generation applications, which are used within a variety of industries, from cosmetic surgery to fluid dynamics to cutting and welding. Ophir smart displays or PC interfaces, including the Nova II, Vega, and Juno, can be used with the sensor. When plugged into one of the company's measurement sensors, a smart connector interface automatically configures and calibrates the display.

"Ophir's PE-C family of pyroelectric sensors continues to break new ground with innovative technology that leads the industry and keeps pace with high performance applications," said Ephraim Greenfield, CTO, Ophir Photonics.

"The F-PE80BF-DIF-C delivers average powers to 200W, three times that of competitors, as well as repetition rates up to 250Hz, and a maximum pulse width setting of 20ms, four times that of competitors."
