Laser Speckle Reducers

Edmund Optics (EO), the premier provider of optical components, introduces new Laser Speckle Reducers.  These versatile devices are ideal for a wide variety of beam homogenization, 3D scanning, metrology, microscopy and interferometry applications.

Diffusing angles of 1°, 10° and 20°
Edmund Optics' Laser Speckle Reducers remove local interferences and greatly reduce speckle noise in laser systems.  This is done by dynamically diffusing the laser beam.  Diffusing angles of 1°, 10° and 20° are offered, providing maximum versatility for a wide range of uses.  Laser Speckle Reducers are compact for ease of handling and integration.  They feature integrated drive electronics and provide vibration-less speckle reduction.

Laser speckle pattern appears as uniform light distribution
Laser Speckle Reducers utilize four electro-optic polymers, which selectively move each Laser Speckle Reducer's central diffuser along the X and Y axis to form a circular pattern of motion.  As a result, the Laser Speckle Reducers adjust the laser speckle pattern to appear as a uniform distribution of light. To take advantage of maximum laser speckle reduction, the user would position the Laser Speckle Reducers perpendicular to the laser beam and use a collimated laser source with beam diameter equivalent to the Laser Speckle Reducers' clear aperture.
