Laser Speckle Reducers
Nov 2011Edmund Optics Inc.Request Info
Edmund Optics has introduced laser speckle reducers suitable for beam homogenization, 3-D scanning, metrology, microscopy and interferometry applications. They remove local interferences and reduce speckle noise in laser systems by dynamically diffusing the laser beam. Diffusing angles of 1°, 10° and 20° are offered. Compact, for ease of integration, they feature integrated drive electronics and vibrationless speckle reduction. They use four electro-optic polymers that selectively move each laser speckle reducer’s central diffuser along the X- and Y-axes to form a circular pattern of motion. For maximum speckle reduction, the user positions the instrument perpendicular to the laser beam and focuses a collimated laser source with a beam diameter equivalent to the reducer’s clear aperture.
