First built-in photodiode trigger for beam-profiling cameras

Ophir-Spiricon has announced the industry's first built-in photodiode trigger for beam-profiling cameras. The trigger is part of the company's USB 2.0 Silicon CCD Cameras designed specifically for laser-beam measurement applications, the SP503U and SP620U. These cameras accurately capture and analyze wavelengths from 190 to 1550 nm, both continuous wave (CW) and pulsed mode.

The built-in photodiode trigger includes new firmware that analyzes background lighting and provides offsets, allowing reliable triggering on a variety of energy levels, including energies as low as 10 µJ. It also includes a pretrigger function that predicts when the next pulse will arrive and opens the shutter in time to see short, ns pulses. The SP cameras feature the highest dynamic range in the industry, up to 64 dB, and a programmable, high-speed electronic shutter.

PRESS RELEASE

Ophir-Spiricon, the global leader in precision laser measurement equipment, today announced the industry's first built-in photodiode trigger for beam profiling cameras at LASER World of Photonics. The trigger is part of the company's USB 2.0 Silicon CCD Cameras designed specifically for laser beam measurement applications, the SP503U
and SP620U. These cameras accurately capture and analyze wavelengths from 190 - 1550nm, both continuous wave (CW) and pulsed mode.

The SP camera's built-in photodiode trigger includes new firmware that
analyzes background lighting and provides offsets, allowing reliable
triggering on a variety of energy levels, including energies as low as 10 µJ. The internal photodiode trigger also includes a pre-trigger function that predicts when the next pulse will arrive and opens the shutter in time to see short, ns pulses.

"The new built-in photodiode trigger for the SP cameras is the most
sensitive in the industry," stated Gary Wagner, President of Ophir-Spiricon Inc. "It can be triggered from something as low contrast as reflected light around a lab setup. This means a user can set the camera up in front of a pulsed laser, turn on the beam profiling program, and capture scattered laser light at even the most challenging nanosecond pulse widths."

Ophir-Spiricon provides the only photodiode triggers in the industry. Two options are available: the new SP cameras' built-in trigger that can synch up to 1000Hz, and an external trigger than can synch to 500Hz. If the lab setup is such that scattered light from the laser does not get to the built-in photodiode, the external photodiode trigger can be used and placed in a different location from the camera.

SP503U and SP620U Beam Profiling Cameras

Ophir-Spiricon's SP cameras feature the highest dynamic range in the
industry, up to 64dB, and a programmable, high-speed electronic shutter. The new beam profiling cameras include the easy to setup, easy to use USB 2.0 interface. They are available in two, ultra-slim versions: the SP503U has a resolution of 640 x 480 pixels, and the SP620U has a resolution of 1600 x 1200 pixels, over 1.9 million pixels, the highest in the industry. Both cameras include a set of filters that allow for effortless measurement of power levels, from microwatts to watts, when used in combination with the automatic shutter and gain control.

The cameras also include the industry's most advanced beam analysis
software, Ophir-Spiricon's LBA, BeamStar, or BeamGage. BeamGage, the next generation of laser beam analysis systems, is the industry's first beam profiling software to be newly designed, from scratch, using the most advanced tools and technologies. Based on UltraCalTM, Ophir- Spiricon's patented baseline correction algorithm that helped establish the ISO 11146-3 standard for beam measurement accuracy, BeamGage provides high accuracy results, guaranteeing the data baseline (zero-point reference) is accurate to 1/8th of a digital count on a pixel-by-pixel basis.

Pricing and Availability

The SP503U and SP620U USB 2.0 CCD cameras are available now. Both cameras include the new built-in photodiode trigger and a choice of beam analysis software packages: LBA, BeamStar, or BeamGage. OEM pricing is provided on request.
