Ophir-Spiricon LLC has announced BeamMic, a laser beam analyzer that combines the essentials for beam analysis in an entry-level system. It includes software that measures a beam’s size, shape, uniformity and mode content.

Beam intensity profiles are displayed simultaneously in 2- and 3-D. Statistical analyses can be performed on measurement functions, and minimum/maximum limits can be set for pass/fail testing. Results are logged and can be exported to industry-standard formats. A configurable report generator allows cutting and pasting of results, images and settings. BeamMic software is integrated with one of four Spiricon USB CCD cameras designed for beam measurements.

Displays are continuously zoomable and resizable, shown in satellite windows on one or multiple monitors. The system performs ISO measurements and test methods on lasers, including beam width, beam diameter, power/energy distribution and spatial orientation. Statistical analysis can be performed on all measurements, such as mean, standard deviation and minimum/maximum.

Setup is fast and easy using the auto setup function. The software automatically sets the gain and exposure time of the camera array to maximize the beam signal while keeping it below saturation.

The system supports the 64- and 32-bit versions of Windows Vista and Windows 7, enhancing system configuration options and increasing processing speed. The software also provides native language support for English, Japanese and Chinese, and is compatible with the German Windows Vista and Windows 7 environments.

BeamMic is based on the proprietary and patented UltraCal baseline correction algorithm that helped establish the ISO 11146-3 standard for beam measurement accuracy. The system guarantees that the data baseline (zero-point reference) is accurate to ? of a digital count on a pixel-by-pixel basis.
