A head-up display device is provided which can suppress error in the attachment position of a fixed mirror. This head-up display device is provided with a display which emits display light, a first mirror which reflects display light from the display, a second mirror which is provided rotatably about a rotation axis and which reflects towards a window shield the display light reflected by the first mirror, a mirror support unit which supports the first mirror, a holding case unit which holds the second mirror and which is formed integrally with the mirror support unit, and plate springs which fix the first mirror to the mirror support unit by pressing the first mirror towards the mirror support unit.

A mounting apparatus for attaching a rearview assembly to a windshield may comprise a wedge; a mount configured to support the rearview assembly, the mount in contact with the wedge on at least one surface; and a spring comprising two legs with bent surfaces and configured to deflect outward from one another upon installation and having a lobe at the end of each leg, the spring configured to secure the mount to the wedge. The wedge may be configured to support the spring.

A head-up display includes a mirror body, a mirror having a shaft serving a rotary axis, a bearing member which holds the shaft of the mirror to be rotatable, a torsion spring through which the shaft penetrates and which urges the mirror in a predetermined rotational direction of the rotary axis with respect to the bearing member, and a housing which accommodates the mirror, the bearing member, and the torsion spring. The torsion spring is disposed on an opposite side opposite to the mirror with respect to the bearing member. The bearing member includes a protrusion to which one end of the torsion spring is hung. The housing includes a depressed portion fitted to the bearing member to fix the bearing member.

A method for forming a reflective element for a vehicular interior rearview mirror assembly includes providing a roll of an ultrathin glass sheet, the ultrathin glass sheet having a thickness dimension of less than or equal to 0.8 mm and greater than or equal to 0.3 mm. An elongated sheet of transparent plastic material if formed. The elongated sheet has a planar first side and a planar second side opposite the planar first side and separated from the planar first side by a thickness of the elongated sheet. The ultrathin glass sheet is unrolled from the roll of the ultrathin glass sheet and the unrolled ultrathin glass sheet is applied to the first side of the elongated sheet. A reflective layer is applied to the second side of the elongated sheet.

A method for an imaging module can include rotating an imaging assembly that includes an imaging device about a first pivot point of a bracket to a select first orientation, fastening the imaging assembly to the bracket at the first orientation, rotating a mirror assembly that includes a mirror about a second pivot point of the bracket to a select second orientation, and fastening the mirror assembly to the bracket at the second orientation. An adjustable, selectively oriented imaging assembly of a first imaging module can acquire images using an adjustable, selectively oriented mirror assembly of a second imaging module.

Laser apparatus (10) includes at least: a laser oscillator that emits laser light (LB); reflection mirrors (M1), (M2) that are disposed on an optical path of laser light (LB) and change the optical path; actuators (ACT1), (ACT2) that are respectively coupled to reflection mirrors (M1), (M2) and displace reflection mirrors (M1), (M2); optical axis deviation detector (16) that is disposed to surround the optical path of laser light (LB) and detects an optical axis deviation of laser light (LB); and a controller that drives actuators (ACT1), (ACT2) on the basis of a detection result of optical axis deviation detector (16) to displace reflection mirrors (M1), (M2) and correct the optical axis deviation of laser light (LB).

The present disclosure provides a microscope interchangeable collector lens device, including a microscope base, a collector lens base, a collector lens, and a wrench, wherein the collector lens base is fitted and installed on the microscope base, the collector lens is mounted on the collector lens base, and the wrench is rotated to rotate the collector lens, so that the collector lens is tightened or loosened, so as to achieve the interchangeability of the collector lens, which can be correctly, smoothly and repeatedly positioned to meet the requirements of the user, with the advantages of easy operation, simple structure, strong function and low cost.

The micromirror device includes: a movable portion having a mirror portion on which a reflecting surface for reflecting incident light is formed; a first support portion that is connected to the movable portion on a first axis located in a plane including the reflecting surface of the mirror portion in a stationary state, and that swingably supports the movable portion around the first axis; and a pair of first actuators that are connected to the first support portion and face each other across the first axis, each of which being a piezoelectric drive type first actuator that allows the movable portion to swing around the first axis, in which in a case where the movable portion swings around the first axis, at least a part of the first actuator swings around the first axis in a phase opposite to a phase of the movable portion, and assuming that a ratio of a rotation angle of the first actuator to a rotation angle of the movable portion is R, 0<R<1.00 is satisfied.
