The present invention relates to a top-contacted reflective sheet device, which is consisted of a base, a reflective sheet and a shaft group, and an angle adjustment module is further included. By the composition of above elements, a level and a flip angle of the reflective sheet is provided to be adjusted easily, and a top end of the reflective sheet could be fixed on a windshield of a vehicle to thereby remove shakes, so that a user may easily adjust the direction of the reflective sheet to obtain an optimal viewing angle, to thereby improve driving safety.

An improved mount for, and method of mounting, an optical structure having a grooved/relieved protruding member is provided. The mount may have the grooved/relieved protruding member extending from a surface of the optical structure, a base element for mounting the mount to another structure and an upper element extending from the base element having a first opening extending therethrough for receipt therein of at least a portion of the grooved/relieved member. The first opening defines first and second arms, each of the arms comprising a head portion and each of the head portions ending at an end. A second opening in the upper element extends through one of the head portions and the end thereof in a direction toward the other head portion, while a third opening exists in the upper element through the end of the other head portion in an orientation substantially opposite to and in communication with the second opening so that a tightening mechanism may be received through the second opening and the third opening. Tightening of the tightening mechanism into the third opening causes the ends of the head portions to draw toward each other so that the first opening of the upper element tightens around the at least a portion of the grooved/relieved protruding member.

An opto-mechanical apparatus including a hollow housing member having a first end and a second end, the housing member having a longitudinal axis, a parabolic mirror positioned on a side of to the first end of the housing member, and a mirror adjustment mechanism attached to the second end of the housing member, the mirror adjustment mechanism connected to the parabolic mirror through the housing member, the mirror adjustment mechanism configured to adjust an axial position of the parabolic mirror along the longitudinal axis and to adjust a radial position of the parabolic mirror about the longitudinal axis.

An optical mount for holding an optical element includes a mounting block having an aperture and an optical element adapted to fit within the aperture. A retaining clip is secured to the mounting block and extends across the optical element. The clip is a thin sheet of flexible material comprising contact straps that overlie edge portions of the optical element. The clip is connected to the mounting block by fasteners.

A light scanning device includes a light source, a deflector, a reflection mirror, and a light width regulating portion. The light source includes a plurality of light-emitting elements located at intervals one another. The deflector deflects to scan by reflecting a plurality of light beams. The plurality of light beams are emitted from the respective light-emitting elements. The reflection mirror is located in an optical path between the light source and the deflector and guides the plurality of light beams emitted from the plurality of light-emitting elements to the deflector. The light width regulating portion regulates widths of the plurality of light beams reflected by the reflection mirror in a main-scanning direction. The light width regulating portion is located adjacent to a reflecting surface of the reflection mirror and includes a pair of regulating wall portions located opposed one another in the main-scanning direction.

The present invention is an improved rear view mirror that removably attaches to a protective helmet. The helmet mirror, in its preferred embodiment, includes a bracket, an elongated adjustable arm, an adjustment nut, and a mirror, wherein the bracket and the adjustable arm are rubber-coated. The adjustable arm includes a first end and a second end, wherein the first end is attached to the bracket and the second end is attached to the mirror by means of the adjustment nut. The positioning of the mirror may be adjusted by bending the adjustable arm and/or pivoting the mirror about the adjustment nut. The bracket is bent to form a general J-shape when viewed from the side. The bracket is adapted to be wedged under the rim portion of a protective helmet to removably secure the device to the same.

A mirror assembly is disclosed. The mirror assembly includes a housing and a mirror that are movable with respect to one another. The mirror assembly includes a plurality of primary adjustment mechanisms. Each primary adjustment mechanism includes a conical washer, a hollow adjuster screw comprising external threads configured to threadedly engage the housing, a wave spring fitting over said hollow adjuster screw, a jam nut seated atop said wave spring, and a spherical head screw configured to threadedly engage the mirror.

Kinematic mounts are used frequently to hold objects such as mirrors, lenses, and other optical equipment. To adjust kinematic mounts, adjustment mechanisms are often required. Adjustment mechanisms can be used to make fine adjustments in applications where precision is required (e.g., laser system prototyping). Kinematic mounts that include never-before implemented form factors and structural elements require new adjustment solutions. This application describes systems that include both novel kinematic mounts as well as new adjustment mechanisms developed to reorient the new kinematic mounts. Adjustment mechanisms described in this application include a main body, a control frame, and control screws to adjust the orientation of the control frame. The control frame is coupled with a kinematic mount's housing, which rotates about a center of curvature of a bottom surface of the housing.

A bipod flexure mount couples an optic to a base while isolating the optic from strain to resist wavefront error. The bipod flexure mount has a distal attachment pad to be coupled to the optic and a proximal attachment pad to be coupled to the base. A pair of beams extend between and couple the distal and proximal attachment pads. The distal attachment pad, the proximal attachment pad and the pair of beams are disposed in and define a planar layer with opposite planar surfaces that are substantially parallel. The bipod flexure mount is relatively flexible about four degrees of freedom and is relatively stiff about two degrees of freedom.
