Ophir Photonics Introduces New Pyroelectric Laser Energy Sensors

Published on July 24, 2013 at 6:51 AM

Ophir Photonics, global leader in precision laser measurement equipment and a Newport Corporation brand, today announced two new Pyroelectric Laser Energy Sensors, the PE50BB-DIF-C and the PE50-DIF-ER-C.

PE50

They complete Ophir's PE-C line of pyroelectric pulsed laser sensors – compact devices that provide the industry's lowest measurable energy, longest measurable pulse width, and highest accuracy. The PE50-DIF-ER-C measures average power to 60W and has a wide dynamic range that extends to infrared lasers, including 2.94µm Erbium laser pulses. The PE50BB-DIF-C features a spectrally flat BB (broadband) coating, usable from far UV to far IR.

"The PE50BB-DIF-C and PE50-DIF-ER-C are the latest additions to Ophir's advanced PE-C line of pyroelectric sensors," stated Ephraim Greenfield, CTO, Ophir Photonics. "They can measure single or repetitive pulses with unprecedented flexibility of dynamic range, pulse rate, and pulse width."

The new laser energy sensors feature large, active aperture areas to 46mm and support pulse widths up to 20ms. They have a user adjustable threshold that prevents false readings in noisy environments. In addition, the sensors
provide:

  • PE50-DIF-ER-C: Repetition rates up to 10kHz, energy measurement down to 100µJ, special diffuser for high damage thresholds up to 20J/cm2 for 300µs pulses.
  • PE50BB-DIF-C: Energies down to 0.1mJ and flat spectral response from 0.19 to 20µm with diffuser removed. With diffuser, energy densities of up to 3J/cm² for nanosecond pulses.

The PE-C laser energy sensors are designed for high power, short pulse YAG and harmonic generation applications in a broad range of industries, as well as long pulse lasers for applications from dermatology to micromachining to industrial welding.

The PE50BB-DIF-C and PE50-DIF-ER-C laser sensors work 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 PE50BB-DIF-C and PE50-DIF-ER-C laser energy sensors are available now.
OEM pricing is available on request.
