An assembly, for example in a microlithographic projection exposure apparatus, comprises an optical element and a joint arrangement for mechanically bearing the optical element. The joint arrangement comprises at least one connecting element secured on the optical element. The mass of the connecting element is distributed over its length so that the moment of inertia of the connecting element is increased in comparison with a connecting element of identical mass and length in which the mass is distributed uniformly over the length.

An optical assembly includes a holder on which an optical element that reflects light traveling to one side in a first direction to one side in a second direction intersecting with the first direction is mounted, a support that supports the holder, a fixed body that supports the support, a first swing mechanism that swings the support about a first swing axis with respect to the fixed body, a first magnet on any one of the holder, the support, and the fixed body, and a first magnetic body on another one of the holder, the support, and the fixed body. At least portions of the first magnet and the first magnetic body overlap each other when viewed from any one of the first direction, the second direction, and a third direction intersecting with each of the first direction and the second direction.

Disclosed are a light receiving module and a light detection and ranging (LIDAR) including the same. The light receiving module according to one embodiment of the present disclosure includes a receiving lens configured to receive external light, a reflective mirror configured to selectively reflect some of the light received by the receiving lens, and a detector configured to detect the light reflected by the reflective mirror, wherein the reflective mirror includes a mirror body having a first surface on a side on which the light received by the receiving lens is incident and a second surface on an opposite side of the first surface, a reflective layer provided on the first surface to reflect light in a designed wavelength region selected according to a predetermined criterion among the light received by the receiving lens, and to transmit light in a noise wavelength region other than the designed wavelength region, and a transmissive layer provided on the second surface so that the light in the noise wavelength region that has passed through the mirror body is transmitted.

Disclosed is a spatial division structure. A spatial division structure according to an exemplary embodiment of the present invention is mounted to divide a reflective surface of a rotary reflection structure provided in the form of a polyhedron and configured to reflect light and includes a blocking plate having therein an insertion space into which the rotary reflection structure is inserted, the blocking plate having a board shape extending in a direction perpendicular to a rotation axis of the rotary reflection structure from the reflective surface to divide the reflective surface into a first reflective surface and a second reflective surface, and frames configured to fix a position of the blocking plate to the reflective surface, in which the frames include one or more first frames connected to the blocking plate and positioned at a lateral side of the first reflective surface, the one or more first frames extending in a direction of the rotation axis of the rotary reflection structure, and one or more second frames each connected to one end of each of one or more first frames and positioned at an upper side of the first reflective surface, the one or more second frames extending to cross the one or more first frames.

A view redirecting system for use on a mobility device to redirect a user's view to a more favorable orientation is disclosed. One embodiment includes a first structure having a convex first reflective surface, a second structure having a flat second reflective surface and a third structure. The third structure being an adjustable structure and configured for connecting said first and second structures together. The first structure and the second structure are configured to be positioned such that the first reflective surface and the second reflective surface are facing each other at angle up to and including ninety degrees. The third structure configured to maintain the angle. The system is arranged to redirect a user's view from a first line-of-sight to a second line-of-sight by light interacting with the reflective surfaces The system being configured for attachment to a structural member of the mobility device.
