Adding to its Pyrocam family of pyroelectric laser beam profiling cameras, Ophir Photonics announced its Pyrocam IIIHR, at Photonics West. Designed for OEM applications, this camera features a sensitive 160x160 pixel image array that can profile beams up to 12.8mm without the need for reduction optics. The higher resolution, 80µm pixel pitch means it can analyse beams up to 20% smaller.
Both pulsed and CW (continuous wave) lasers can be measured, from 13 to 355nm and 1.06 to over 3000µm, 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 cameras. A 16b ADC provides reliable measurement and analysis of both large and low level signals in the wings of the laser beam. A SNR 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.
“Lasers are increasingly embedded in novel systems where traditional technologies have not been able to keep up with the pace of miniaturisation,” said Gary Wagner, General Manager, Ophir Photonics. “In semiconductor device fabrication, the physical limits of transistor scaling are challenging the exponential improvements predicted by Moore's Law. Fibre, CO2, and solid state lasers are now used to drill, cut, and ablate ever thinner chip layers. At the other end of the spectrum, long wavelength terahertz lasers are being applied to chemical analysis, medical imaging, and wireless communications.”
The Pyrocam IIIHR pyroelectric laser beam profiling camera is available now, with OEM prices available on request.
