USB 2.0 Silicon CCD cameras

Ophir-Spiricon has launched two new USB 2.0 Silicon CCD cameras designed specifically for laser beam measurement applications. The SP503U and SP620U cameras accurately capture and analyse wavelengths from 190nm-1550nm, both for continuous wave (CW) and pulsed mode. Gain control is either automatic or manual, accommodating the widest range of input levels. The cameras feature the highest dynamic range in the industry, up to 64dB, and a programmable, high-speed electronic shutter. Both cameras also include a photodiode synch to capture scattered laser light at fast nanosecond pulse rates.

A USB 2.0 interface is provided, which is easy to set up and use. The cameras are available in two, ultra-slim versions: the SP503U with a resolution of 640 x 480 pixels, and the SP620U, which has a resolution of 1600 x 1200 pixels, more than 1.9 million pixels in total. Both cameras include a set of filters that allow for measurement of power levels, from microwatts to watts, when used in combination with the automatic shutter and gain control. The cameras also include multiple mounting options to fit any laser measurement application.

The SP503U and SP620U USB CCD cameras are supported by advanced beam analysis software. Users have a choice between Ophir-Spricon's LBA and BeamStar software packages.

LBA software contains all the algorithms and calculations necessary to make highly accurate measurements, as well as an ActiveX interface to extract data into other applications, 2D and 3D viewing, reference subtraction, user-customised apertures and colour palettes, and Z-axis scaling.

BeamStar is easy to use and provides a single interface to a wide range of measurement options. The software includes power measurements, beam width, 2D Top Hat and 2D Gaussian measurements, Beam Wander measurement and logging, M2 measurements, and simultaneous 2D and 3D displays.
