Ophir Photonics, global leader in precision laser measurement equipment and a Newport Corporation company, has announced the newest member of the Pyrocam family of pyroelectric laser beam profiling cameras at Photonics West, the Pyrocam IIIHR. Designed for OEM applications, this camera features a sensitive, 160 x 160 pixel image array that can profile beams up to 1/2-inch (12.8 mm) without the need for reduction optics. The higher resolution, 80µm pixel pitch means it can analyze beams up to 20% smaller. Both pulsed and CW (continuous wave) lasers can be measured, from 13 to 355 nm and 1.06 to >3000 µm, including CO2 lasers, telecom NIR lasers, and THz sources.

The Pyrocam IIIHR allows users to see the beam for dynamic alignment and proper operation. For high-speed applications, it includes an interface to GigE (Gigabit Ethernet) cameras. A 16-bit A/D converter provides reliable measurement and analysis of both large signals and low level signals in the wings of the laser beam. A signal to noise ratio of 1000:1 means beams of 30mW/cm2 are easily visible.

The Pyrocam IIIHR ships with BeamGage, the company's advanced laser beam analysis software. BeamGage includes more than 55 measurements and calculations, many based on ISO standards. These include fast, off-axis correction of distorted beam images; trend charting; data logging; power/energy calibration; and pass/fail production testing. Laser manufacturers and OEMs can easily import their own custom algorithms created in C#/.NET using Custom Computations. BeamGage is based on the patented UltraCal baseline correction algorithm that helped establish the ISO 11146-3 standard for beam measurement accuracy.
