Large Format Beam Waist Analyzer Camera (BWA-CAM)

The Large Format Beam Waist Analyzer Camera (BWA-CAM) is intended for use with high power, multimode fiber or diode lasers that have large focal spot sizes. The 25 megapixel sensor has an active area of ≈ 23mm x 23mm. This permits the ability to measure a 1 mm diameter focal spot size with ISO 11146-1 (2005) compliance. If ISO compliance is not important, it provides the user the ability to see more than one Rayleigh range of a large spot > 1mm.
