The diffusor is mounted in a thin steel frame. Speckle Reducer. Many times one wanst to illuminate an object with high intensity and even illumination. Lasers have the intensity but are too coherence and cause speckle. A way to get around this is to use the Speckle Reducer, SK11. This optical device is totally passive.

Electro-active polymer LSR. Optotune Laser Speckle Reducers Ideal for Eliminating Laser Speckle Noise Plug and Play with Integrated Drive Electronics 6 - 24 Degree Diffusing Angles Available 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. 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 LS R-1000 series is fed with two control electrical signals that selectively move the central diffuser in x- and y- direction.

Founded in 2008, we started out with our core technology of focus tunable lenses, which was inspired by the working principle of the human eye. Optotune laser speckle reducers remove local interferences and significantly reduce speckle noise in laser systems by dynamically diffusing the laser beam. Offering a compact size, integrated drive electronics, and vibration-less speckle reduction, Optotune laser speckle reducers are ideal for beam homogenization, 3D scanning, metrology, microscopy, and interferometry. Rotating diffusers—which destroys the spatial coherence of the laser light—can also be used to reduce the speckle.

Each fiber length differs by more than the coherence length of the laser. The SK11 is an excellent source for microscopic illumina-tion. Laser Speckle Reducer LSR-3000 Series Speckle noise from a laser-based system is reduced by dynamically diffusing the laser beam.

The XLR 960ix laser-scanner integration tests demonstrated a 30% reduction of the speckle contrast, which supports EPE improvements on the product as designed. FIGURE 5.
