Abstract
A 50-μ glass filament from a fiber-optics bundle, bent at 90° near the lower end and fastened to an adjustable support, proves to be a better light pickup than the usual pinhole aperture for high-resolution scanning of a laser beam. Scans of a 50-mW laser beam were used to develop a spatial filter combined with a short-focus collimating lens which yields a uniform, Gaussian-shaped beam with no increase in size.Keywords
