The field of view (FoV) of a lobster-eye optic, which is the solid angle subtended by the optic plate to the curvature center, is limited only by the optic size for a given curvature radius. Since the micropore optics are spherically symmetric in essentially all directions, theoretically, an idealized lobster-eye optic is almost free from ...
A q-plate is an optical device that can form a light beam with orbital angular momentum (OAM) from a beam with well-defined spin angular momentum (SAM). Q-plates are based on the SAM-OAM coupling that may occur in media that are both anisotropic and inhomogeneous , such as an inhomogeneous anisotropic birefringent waveplate .
Corrector plate: A full aperture negative lens placed before a primary mirror designed to correct the optical aberrations of the mirror. Schmidt corrector plate: An aspheric-shaped corrector plate used in the Schmidt telescope. Meniscus corrector: A meniscus-shaped corrector plate usually used in the Maksutov telescope.
The q-plate with topological charge q can generate a charge vortex based on the input beam polarization. An s-plate is a similar technology to a q-plate, using a high-intensity UV laser to permanently etch a birefringent pattern into silica glass with an azimuthal variation in the fast axis with topological charge of s. Unlike a q-plate, which ...
Fans of a certain school in a neighboring state are thrilled. “Best thing Kansas can do is release a black and gold license plate. #MIZ.”
That’s because the state has strict rules for what goes on custom license plates. Of the 1.1 million new Missouri passenger vehicle registrations processed during 2023, over 8,000 of them were ...
The crystal is cut into a plate, with the orientation of the cut chosen so that the optic axis of the crystal is parallel to the surfaces of the plate. This results in two axes in the plane of the cut: the ordinary axis , with index of refraction n o , and the extraordinary axis , with index of refraction n e .
Malibu Feed Bin, a landmark pet food store with a retro 70s vibe along the Pacific Coast Highway, was completely destroyed, according to a post on its Facebook page. "We lost the Feedbin today ...
