摘要： A partial beam splitter includes a substrate including a substrate material; and a coating arranged on at least one main surface of the substrate. Along a first direction which is parallel to a normal vector of the main surface, the substrate and all coatings having a total thickness. For a specific light beam having a specific wavelength within a range of 450 nm and 650 nm which is incident on the partial beam splitter along a second direction with an angle of 32° enclosed between a vector pointing in the first direction and a vector pointing in the second direction, the specific light beam after transmitting through the partial beam splitter has a phase having a phase difference of an absolute value of smaller than or equal to 30° compared to the case in which, under otherwise identical conditions, the partial beam splitter is replaced by a similar reference substrate.

摘要： A multiplexer includes: an output section outputting a beam bundle made of a plurality of laser beams whose F-axis directions are aligned; and an F-axis converging lens causing the beam bundle outputted from the output section to be converged in the F-axis direction. Optical axes of the plurality of laser beams constituting the beam bundle outputted from the output section intersect with each other at a single point without relying on the F-axis converging lens.

摘要： Systems, devices, and methods for eyebox expansion by exit pupil replication in wearable heads-up displays (“WHUDs”) are described. A WHUD includes a scanning laser projector (“SLP”), a holographic combiner, and an exit pupil selector positioned in the optical path therebetween. The exit pupil selector is controllably switchable into and between N different configurations. In each of the N configurations, the exit pupil selector receives a light signal from the SLP and redirects the light signal towards the holographic combiner effectively from a respective one of N virtual positions for the SLP. The holographic combiner converges the light signal to a particular one of N exit pupils at the eye of the user based on the particular virtual position from which the light signal is made to effectively originate. In this way, multiple instances of the exit pupil are distributed over the eye and the eyebox of the WHUD is expanded.

摘要： Focal plane shift elements and optical systems with focal plane shifting features for illuminating flow-paths in a fluidic processing system are disclosed. An optical system may include a light source providing an incident first light beam. The optical system may include at least one optical element configured to collect and focus the incident first light beam to produce a second light beam having different portions simultaneously focused at two or more different locations along an optical path, with each location corresponding to a different flow-path of the fluidic processing system. The focal plane shift elements and optical systems with focal plane shifting features may be particularly useful in a microfluidic system.

摘要： First and second optical films in a stack each have a structured surface defining extended Fresnel lenses. First and second Fresnel lenses of the respective first and second films extend generally parallel to different first and second in-plane axes respectively. The films may be attached together such that light transmitted by one film is intercepted by the other. The film stack may also include a diffuser disposed to scatter light transmitted by the optical film(s). Other disclosed decorative articles include an individual optical film having a structured surface with transmissive facets arranged in a cyclic slope sequence from substantially zero to a maximum positive slope to substantially zero to a maximum negative slope and back to substantially zero, the sequence repeating over some or all of the structured surface. The slope sequence may define alternating focusing and defocusing Fresnel lenses, and the Fresnel lenses may be extended and linear.

摘要： Apparatus and methods for combining beams of amplified radiation are disclosed. A beam combiner has a collimating optic positioned to receive a plurality of coherent radiation beams at a constant angle of incidence with respect to an optical axis of the collimating optic. The respective angles of incidence may also be different in some embodiments. The collimating optic has an optical property that collimates the beams. The optical property may be refractive or reflective, or a combination thereof. A collecting optic may also be provided to direct the plurality of beams to the collimating optic. The beam combiner may be used in a thermal processing apparatus to combine more than two beams of coherent amplified radiation, such as lasers, into a single beam.
