This phenomena occurs due to the coherence of the light and seems to be inevitable. SK-11 reduces speckle noise and improves your image quality. 2021-03-01 Laser Speckle Reducer LSR-1000 Series Speckle noise from a laser -based system is reduced by dynamically diffusing the laser beam . The LS R-1000 series is fed with two control electrical signals that selectively move the central diffuser in x- and y- direction. Optotune's laser speckle reducers are the ideal choice for: Laser projection displays from cinema to pico . Head-up displays. Beam homogenizer.
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. Optotune’s LSR-4C speckle reducer has an aperture of 18.5×18.5 mm and is especially suitable for applications where high laser powers and large beam diameters are used. The diffusor is … 4. SCANNING SPECKLE REDUCERS One method to reduce speckle involves scanning a beam on a diffuser rather than scanning the diffuser on the beam. This has been suggested by Peled8, and Figure 2 illustrates one way to incorporate a Micro Electro-Mechanical System (MEMS) mirror into such a design. The incoming, collimated laser beam passes through a beam Laser speckle reducers, 2D .

Optotune's laser speckle reducer is the ideal choice for application in laser projection displays, beam homogenizers, metrology, microscopy, interferometry and lithography. Optotune's laser speckle reducers can be tailored to your specific demands in terms of size, oscillation frequency or transmission range - contact Pacer for details. 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. Optotune’s LSR-4C speckle reducer has an aperture of 18.5×18.5 mm and is especially suitable for applications where high laser powers and large beam diameters are used. The diffusor is mounted in a thin steel frame. The in-line laser speckle reducer (fiber optical beam homogenizer, or De-Speckler) is an all-fiber Simple system for laser speckle reduction Published by Optics for Hire.
