Edmund Optics’ Laser Speckle Reducers dynamically diffuse laser beams to reduce speckle noise. The devices can be used in beam homogenization, 3-D scanning, metrology, microscopy, and interferometry applications to remove local interferences. Diffusing angles of 1°, 10°, and 20° provide maximum versatility for a range of uses. The units use 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 system adjusts the pattern to appear as a uniform distribution of light. The compact devices feature integrated drive electronics and provide vibration-less speckle reduction.

Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
