A correction mask for an optical beam homogenizer includes a lens array. The correction mask is configured to provide a shaped initial beam profile. A subset of a plurality of optical paths between the incoming light beam and the illumination plane is at least partially blocked by the correction...
PROPAGATION METHOD OF SHAPED BEAM USING HOMOGENIZER AND LASER PROCESSING OPTICAL SYSTEM USING THE SAME PROPAGATION METHOD OF SHAPED BEAM USING HOMOGENIZER AND LASER PROCESSING OPTICAL SYSTEM USING THE SAMEPROBLEM TO BE SOLVED: To dissolve the problem that when there is slight decentering, beams become...
Different methods have been introduced to reduce the speckle contrast including the use of a homogenizer and beam splitter, piezoelectric actuators and a rotating diffuser [49]. The electrical 3-dB bandwidth of three bespoke RGB LDs used for VLC in Ref. [3] is measured to be 230 MHz, 780 ...

When connecting a multi-furcated fiber to a spectrometer or light source, light entering/exiting each of the fiber legs may or may not be uniform, so a fiber-optic homogenizer can be used to mix the signals to provide more uniform signal. The ... Compare this product See the other pro...
OLS presents optical systems aimed for delivery of high power UV, IR beams and related components as beam homogenizers, 2D scanning mirrors, beam choppers, self-cleaning window for vacuum chambers
The collimator is an electromechanical optical device installed in the output window of the tube sleeve of the x-ray tube assembly. Its main function is to control the X-ray beam output field of the X-ray tube to satisfy the X-ray imaging diagnos...
Such proposed design allows making use of only a primary parabolic mirror + a homogeniser to concentrate and redistribute the sunlight, representing a large departure from virtually all of the previous studies. Specifically, such homogeniser can furcate the light beam into the small channels/...
