Laser Speckle Reducer

Offering a compact size integrated drive electronics and vibration less speckle.

Laser speckle reducer.

The in line laser speckle reducer fiber optical beam homogenizer or de speckler is an all fiber passive component which can efficiently homogenize speckle pattern and reduce unwanted modal noise striations hot spots and beam non uniformity within a multimode optical fiber producing a stable output beam that has fewer speckle hot spots and more uniform energy intensity profile. This phenomena occurs due to the coherence of the light and seems to be inevitable. Laser speckle reducers 2d. Laser speckle reducers 2d mirrors tunable.

When a coherent light source illuminates an object speckle noise appears and degrades your important images. Offering a compact size integrated drive electronics and vibration less speckle reduction optotune laser speckle reducers are ideal for beam homogenization 3d scanning metrology. Thus annoying speckle noise on detectors and imaging systems can be lowered to a minimum. Optotune develops and manufactures industry shaping active optical components that allow customers around the globe to innovate.

Laser speckle reducer sk 11. 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. Optotune laser speckle reducers remove local interferences and significantly reduce speckle noise in laser systems by dynamically diffusing the laser beam. The basis of this approach is a single thin steel structure that is brought into resonance by pulsing an actuating coil with current which generates a strong.

Sk 11 consists of a fiber bundle of different length fibers. Lasers have been adopted for use in a wide range of applications such as projectors and automotive products in recent years because of their high brightness high. 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. Launched in 2016 the reluctance force laser speckle reducer is particularly suitable for applications that require large format glass diffusers.

Optotune laser speckle reducers remove local interferences and significantly reduce speckle noise in laser systems by dynamically diffusing the laser beam. Katsunori nakata has developed a speckle reduction module for the projector industry which is seeing a transition to laser light sources. Sk 11 reduces speckle noise and improves your image quality. Optotune s laser speckle reducer is the ideal choice for application in laser projection displays beam homogenizers metrology microscopy interferometry and lithography.

Reluctance force laser speckle reducer. If a photographic plate or another 2 d optical sensor is located within the scattered light field without a lens a speckle pattern is obtained whose characteristics depend on the geometry of the system and the wavelength of the laser. When laser light which has been scattered off a rough surface falls on another surface it forms an objective speckle pattern.
