Sk 11 consists of a fiber bundle of different length fibers.
Laser speckle reducer.
Launched in 2016 the reluctance force laser speckle reducer is particularly suitable for applications that require large format glass diffusers.
Laser speckle reducers 2d.
Sk 11 reduces speckle noise and improves your image quality.
The minimum speckle contrast ratio observed using our method was 0 11 for the dpss laser and 0 06 for the ld.
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.
Offering a compact size integrated drive electronics and vibration less speckle reduction optotune laser speckle reducers are ideal for beam homogenization 3d scanning metrology.
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.
Thus annoying speckle noise on detectors and imaging systems can be lowered to a minimum.
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.
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.
When a coherent light source illuminates an object speckle noise appears and degrades your important images.
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.
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.
Laser speckle reducers 2d mirrors tunable.
Reluctance force laser speckle reducer.
Optotune s laser speckle reducer is the ideal choice for application in laser projection displays beam homogenizers metrology microscopy interferometry and lithography.
The maximum speckle reduction efficiency was found to be 75 6 and 81 25 for a 532 nm diode pumped solid state dpss laser and a 520 nm laser diode ld respectively.
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.
Offering a compact size integrated drive electronics and vibration less speckle.
Optotune develops and manufactures industry shaping active optical components that allow customers around the globe to innovate.
