Laser Energy Sensors offer user-adjustable threshold.May 26, 2011 -
Featuring spectral range of 150 nm to 12 µm, Pyro-C Pyroelectric Laser Energy Sensors cover UV, Visible, and Near IR wavelengths. Model PE10-C has lowest measurable energy down to 1 µJ and repetition rate to 25 kHz with 12 mm aperture. With energies from 8 µJ to 10 J, Models PE24-C/PE50-C offer repetition rates to 10 kHz and pulse widths to 5 ms with 24.5 and 46 mm apertures. Model PE50-DIF-C is similar to PE50-C, but with diffuser to allow high energy densities to 1 J/cm².

Ophir Photonics Group Introduces Pyro-C Line of Laser Energy Sensors; Combine High Damage Threshold, High Repetition Rate, and Widest Range of Wavelengths
Munich, Germany - Ophir Photonics Group, the global leader in precision laser measurement equipment, today announced at Laser World of Photonics the Pyro-C line of Pyroelectric Laser Energy Sensors. An upgrade to the company's PE line of pyroelectric pulsed sensors, the Pyro-C detectors provide the industry's lowest measurable energy, longest measurable pulse width, and highest accuracy. The sensors are compact devices that provide a user adjustable threshold, preventing false readings in noisy environments.
Like the PE Series before it, the Pyro-C sensors are the only laser energy detectors in the industry to combine high damage threshold and high repetition rates with the widest range of wavelengths, from UV to Near IR.
They accurately measure high repetition rate lasers over the broadest spectral range - 150nm to 12µm. The Pyro-C line includes:
PE10-C: lowest measureable energy, down to 1µJ, high repetition rates to 25kHz, 12mm aperture
PE25-C/PE50-C: energies from 8µJ to 10J, repetition rates to 10kHz, pulse widths to 5ms, 24.5mm and 46mm apertures
PE50-DIF-C: similar to PE50-C but with diffuser to allow high energy
densities to 1J/cm2
Each product above is also available in a version that features a high damage threshold BF coating. The models are the PE10BF-C, PE25BF-C, PE50BF-C, PE25BF-DIF-C, PE50BF-DIF-C. This coating allows the sensors to deliver the highest damage thresholds, to 0.8 J/cm2 without diffuser and up to 4J/cm2 with diffuser. It also allows pulse widths to 20ms.
While most high damage threshold detectors require multiple diffusers to cover the spectral range, the Pyro-C sensors use a single diffuser to cover UV, Visible, and Near IR wavelengths. This results in an accurate and flexible system that handles a wide range of measurement requirements.
"Ophir's Pyro-C pyroelectric detectors are high accuracy, high repeatability detectors that can measure millions of pulses with no change in calibration," stated Ephraim Greenfield, CTO, Ophir Photonics Group. "Built-in wavelength correction and high damage thresholds ensure these laser energy sensors provide the accuracy and repeatability needed for a diverse range of laser measurement applications, from photolithography to Nd:YAG laser welding."
The Pyro-C sensors can do virtually everything a standard thermal head can do, such as power measurement with repetitive pulses, single shot energy, and laser power tuning. Users are provided with a wide range of information about the laser being tested, including pulse energy, average power, frequency, minimum and maximum values, missing pulses, time jitter, and standard deviation. Pulse energies can be displayed numerically or in graphs. Up to 50,000 points of data can be stored on-board in nonvolatile memory and can be sent to a computer for analysis and storage.
The Pyro-C line of laser energy sensors works with most Ophir smart displays or PC interfaces, with all new features supported in 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 heads.
