This device measures the characteristics of a line of laser illumination. The device determines uniformity of total and peak energy; uniformity in spot size, focal points, and threshold values; and the length and width of the illumination line. The light of the laser source is led through an optical filter, such as a 99% reflecting mirror, and is subsequently passed through two movable apertures that are perpendicular to each other. The second aperture is on a rotating cylinder that scans the light characteristics for every vertical position of the first slit, composing a complete characteristic recorded by a fixed sensor. The device allows the rapid quality determination of new laser sources and the testing of output characteristics of a laser line source before accepting it in an apparatus. In this fashion, a complete scan of each portion of the line illumination field is recorded.
