PE50-DIF Pyroelectric Detector

Ophir-Spiricon has launched the PE50-DIF Pyroelectric Detector, which is a laser power/energy detector combining high damage threshold and high repetition rates with a wide range of wavelengths, from UV to near IR.  

The PE50-DIF accurately measures high repetition rate lasers over a broad spectral range of 193nm to 2.94µm. The detector measures pulse widths to 10ms and pulse rates to 3,000Hz. While most high damage threshold detectors require multiple diffusers to cover the spectral range, the PE50-DIF uses 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.

The PE50-DIF Pyroelectric Detector features a 35mm aperture. For short pulses, the detector measures repetition rates to 3000Hz with pulse widths of up to 30µs. For long pulses, the detector measures repetition rates to 250Hz with pulse widths of up to 1ms. The PE50-DIF provides a high damage threshold for UV wavelengths and other wavelengths, ranging from 1J/cm2 at <100 ns to 40J/cm2 at 1ms. A high accuracy, high repeatability detector, millions of pulses can be measured with no change in calibration.

The PE50-DIF Pyroelectric Detector has similar functionality to a standard thermal head, 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 PE50-DIF works with all Ophir smart displays or PC interfaces, including the Orion PE, Nova, Nova II, Vega, LaserStar, USBI, Pulsar, and Quasar. Each display features a 'Smart Connector' interface that automatically configures and calibrates the display when plugged into one of the company's measurement heads.
