Ophir Intros Pyroelectric Laser Sensors with Widest Dynamic Range, Highest Damage Thresholds
Ophir Photonics Group today announced two new Pyroelectric Laser Energy Sensors, the PE50BF-DIFH-C and the PE100BF-DIF-C. They are part of Ophir's PE-C line of pyroelectric pulsed sensors ­ compact devices that provide the industry's lowest measurable energy, longest measurable pulse width, and highest accuracy. The new sensors feature an innovative BF coating and diffuser that deliver the highest damage thresholds: up to 6J/cm2 for nanosecond pulses.
The new PE-C laser energy sensors are designed for high power, short pulse YAG laser and harmonic generation applications in a broad range of industries, from cosmetic surgery to fluid dynamics to cutting and welding.
These compact devices provide a user adjustable threshold, preventing false readings in noisy environments. They support repetition rates up to 250Hz and pulse widths up to 20ms. In addition, the sensors provide:

- PE50BF-DIFH-C: energy measurement down to 200µJ, special diffuser for even higher damage thresholds up to 6J/cm2

- PE100BF-DIF-C: energy measurement down to 0.7mJ, damage thresholds up to
3J/cm2

Ophir broke new ground in the industry with last year's introduction of the PE-C family of pyroelectric sensors that combine highest damage thresholds with high repetition rates and lowest measurable energies, said Gary Wagner, General Manager, Ophir Photonics (U.S.). As next generation lasers employ higher powers and energy levels, measurement becomes even more critical to ensure accuracy and safe operation. These newest sensors keep pace with high performance applications by allowing high energy densities to 6J/cm2.

The PE-C line of laser energy sensors works with most Ophir smart displays or PC interfaces, including the Nova II, Vega, and Juno. Each display features a Smart Connector interface that automatically configures and calibrates the display when plugged into one of the company's measurement sensors.

Availability & Pricing

The PE50BF-DIFH-C and PE100BF-DIF-C sensors are available now. OEM pricing is available on request.
