Publication number: 20150097940Abstract: A system comprises a first beamsplitter module and a second beamsplitter module aligned with the first beamsplitter module along an alignment line. In certain embodiments, each beamsplitter module can split a beam traveling along a first optical path into a first split beam and a second split beam within a spectral range. Each beamsplitter module can transmit the first split beam along the first optical path and direct the second split beam along a second optical path substantially orthogonal to the first optical path and to the alignment line. In certain embodiments, each beamsplitter module can receive a first beam traveling along a first optical path and a second beam traveling along a second optical path that is substantially orthogonal to the first optical path and to the alignment line. Each beamsplitter module can combine the second beam with the first beam to yield a combined beam and transmit the combined beam along the first optical path.Type: ApplicationFiled: December 15, 2014Publication date: April 9, 2015Inventors: Alexander Artsyukhovich, Mikhail Boukhny, Z.

Publication number: 20090234334Abstract: A system, apparatus and method for spatially distributed, spectrally neutral optical attenuation. One embodiment of the apparatus can include: an attenuator fin plate; a set of attenuator fins, wherein each of the fins is operably coupled to the fin plate at a preset fin angle to the fin plate normal such that the attenuator fins maintain their position relative to the fin plate as the fin plate moves; and a motor for rotating the fin plate a set angular distance around an axis of rotation, wherein the axis of rotation is at a preset fin plate angle to a light beam direction of travel and wherein the attenuator fins block varying amounts of the light beam as the fin plate is rotated through the set angular distance. The attenuator fin plate and attenuator fins can be a single, integral component, wherein the attenuator fin plate is etched and stamped to form the attenuator fins, or separately formed components that are attached, for example, to a separate frame.Type: ApplicationFiled: March 24, 2009Publication date: September 17, 2009Inventors: Alexander Artsyukhovich, T.
