Laser profiling camera features 160x160px image array
A laser beam profiling camera, claimed to provide more accurate beam measurements, has been introduced by Ophir Photonics. The Pyrocam IV is the next generation of the Pyrocam family, following the Pyrocam III. The camera, which features a 160x160px image array that can profile beams up to 1/2" (12.8mm), measures both pulsed and continuous wave lasers, from 13-355 and 1.06-3000µm and greater.
The Pyrocam IV, which is suitable for the operation of CO2 and telecomms NIR lasers, includes a 14-bit ADC which provides reliable measurement and analysis of both high and low level signals in the wings of the laser beam. With a signal to noise ratio of 1000:1, beams of 30mW/cm2 are easily visible. The camera also includes an interface to GigE cameras, making it suitable for high-speed applications.
The Pyrocam IV comes with BeamGage, Ophir Photonics' laser beam analysis software. This provides 2D and 3D viewing of beams and includes the algorithms and calculations needed to make accurate, ISO approved, NIST-traceable beam measurements. Measurements include total and peak power/energy, peak and centroid location, beam diameter, and X/Y knife edge beam widths.
"The Pyrocam cameras are the only way to see 3D views of long wavelength lasers, CO2 and beyond," said Gary Wagner, General Manager (U.S.), Ophir Photonics. "The increased sensitivity and longer wavelength range of the Pyrocam IVs make it ideal for the burgeoning terahertz lasers market. Terahertz laser power is increasing in leaps and bounds for a wide range of applications, from chemical analysis and security scanning to medical imaging and telecommunications."
