Ophir Photonics: Laser beam profiling camera
Ophir Photonics, a Newport Corporation brand, announces the Pyrocam; IVs, the newest member of the Pyrocam family of pyroelectric laser beam profiling cameras.
The Pyrocam IVs is the next generation of the popular Pyrocam III. It features a more sensitive, 160 x 160 pixel image array that can profile beams up to ½-inch (12.8 mm) without the need for reduction optics. The Pyrocam IVs measures both pulsed and CW (continuous wave) lasers, from 13 to 355 nm and 1.06 to >3000 µm. An integral focal plane chopper is included for CW beams and thermal imaging.
"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."
The Pyrocam IVs allows you to see the beam for dynamic alignment and proper operation of CO2 and telecom NIR lasers, as well as other infrared sources out to the Far IR THz range. For high-speed applications, it includes an interface to GigE (Gigabit Ethernet) cameras. A 14-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 30 mW/cm2 are easily visible.
The Pyrocam IVs ships with BeamGage®, the company's advanced 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 patented Ultracal® baseline algorithm in BeamGage® eliminates background noise, ensuring the highest degree of measurement accuracy.
