Laser Speckle Reducers
Edmund Optics Inc.Request Info
Edmund Optics has introduced laser speckle reducers suitable for a variety of beam homogenization, 3-D scanning, metrology, microscopy and interferometry applications.
The devices 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. They are compact for ease of handling and integration and 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. As a result, they adjust the laser speckle pattern to appear as a uniform distribution of light. To take advantage of maximum speckle reduction, the user positions the speckle reducers perpendicular to the laser beam and uses a collimated laser source with a beam diameter equivalent to the reducers' clear aperture.
They are USB-powered for convenience and ease of use. Offered in models with either a 5- or a 10-mm clear aperture, they are in stock and available for immediate delivery.
