LOGAN, Utah, June 3, 2011 — Ophir Photonics Group has introduced power/energy measurement and beam profiling systems. Among the new products are the BeamTrack series thermal sensors, which combine power and energy measurement, beam position and beam size in a single compact device.

BeamGage, the company's next-generation laser beam analysis software, supports 64-bit versions of Windows Vista and Windows 7, as well as two camera formats, the 11-megapixel, 35-mm USB L11058 large-format beam profiling camera, and Gigabit Ethernet cameras that provide up to 1-Gb/s transmission rates in a robust, miniature package measuring 34 × 34 × 69 mm. Based on the proprietary and patented UltraCal baseline correction algorithm, BeamGage provides high-accuracy laser measurements, guaranteeing that the data baseline (zero-point reference) is accurate to ? of a digital count on a pixel-by-pixel basis.

The NanoModeScan M2 laser beam propagation analyzer enables quantitative measurement and viewing of high-power CO2 laser beams. It combines the flexibility and speed of Photon Inc.’s NanoScan near-field profiler with dedicated M2 measurement hardware and software. The system is easy to set up and align, and the straight line-of-sight design means that little or no attenuation is required. An M2 measurement can be made in as little as 20 s. The system reports beam waist diameter and location, divergence and the beam’s Rayleigh range for each axis.

A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
1. In optics, the bending of rays away from each other. 2. In lasers, the spreading of a laser beam with increased distance from the exit aperture. Also called beam spread. 3. In a binocular instrument, the horizontal angular disparity between the two lines of sight.
Rayleigh range
In the region of a Gaussian beam focus by a diffraction-limited lens, it is the axial distance from the point of minimum beam waist (Wo) to the point where the beam diameter has increased to .
