Ophir Photonics, a specialist in precision laser measurement equipment and a Newport Corporation brand, announced the PE9-ES-C High Sensitivity Pyroelectric Laser Energy Sensor. The PE9-ES-C is part of Ophir’s PE-C line of compact, pyroelectric pulsed laser sensors that deliver low energies, long measurable pulse widths and high accuracy. The high sensitivity PE9-ES-C measures some of the lowest laser energies in the industry, as low as 50 nanoJoules (nJ). The sensor also accurately measures at high repetition rates, up to 10 kilohertz (kHz). It features a broad spectral range operating from 150 nanometres (nm) to 12 micrometres (µm).
The PE9-ES-C laser energy sensor is designed for low energy, short-pulse YAG and harmonic generation applications, as well as low energy, long pulse lasers. It features an 8-millimetre (mm) active aperture area and supports pulse widths to 20 microseconds (µs). A user-adjustable threshold prevents false readings in noisy environments.
The new sensor 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 range of information about the laser being tested, including pulse energy, average power, frequency, minimum and maximum values, missing pulses and standard deviation. Pulse energies can be displayed numerically or in graphs. Up to 250,000 points of data can be stored on-board in non-volatile memory and can be sent to a computer for analysis and storage.
The PE9-ES-C energy sensor 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.
The PE9-ES-C laser energy sensor is available now. OEM pricing is available on request.
