Actuators for rotating an optical-path-folding-element with two, first and second, degrees of freedom in an extended rotation range around two respective rotation axes, folded cameras including such actuators and dual-cameras including a folded camera as above together with an upright camera.

A folded module includes a housing, a carrier provided in the housing, and a rotation holder provided on the carrier and including a reflective member. The carrier is rotatable, with respect to the housing, around a first axis formed by one rotating shaft ball, the rotation holder is rotatable with respect to the carrier around a second axis formed by two ball members, and the first axis and the second axis intersect each other, and the one rotating shaft ball and the two ball members are provided together on a plane on which both the first axis and the second axis are provided.

An optical unit includes: a reflection portion that reflects an incident light flux incident from outside on a reflection surface in a reflection direction from an incident direction toward an imaging element; a movable body having the reflection portion and a holder supporting the reflection portion; a fixed body; a rotation support mechanism that causes the movable body to rotate with respect to the fixed body with an axial direction as a rotation axis; and a drive mechanism having a magnet and a coil and causing the movable body to rotate with respect to the fixed body. The magnet is provided at a position not contacting the reflection portion in the holder and on a back side of the reflection surface, and has a parallel surface parallel to the reflection surface. The coil is provided at a position opposing the magnet in the fixed body.

Provided is a prism driving device. The prism driving device includes a housing assembly, a prism holder disposed on the housing assembly in an angle adjustable manner, and an electromagnetic driving assembly. The electromagnetic driving assembly includes a magnet portion and a coil portion disposed opposite the magnet portion, where one of the magnet portion or the coil portion is disposed on the prism holder, the other one is disposed on the housing assembly, and the electromagnetic driving assembly is configured to adjust a tilt angle of the prism holder. One of the housing assembly or the prism holder is provided with a support protrusion and the other is provided with a groove, and at least a portion of the support protrusion is magnetically sucked into the groove.

Disclosed is a lens assembly. The disclosed lens assembly comprises: a base; a lens unit which is disposed on one side inside the base and moves forward or rearward in the length-wise direction of the base; an optical path changing unit which is disposed on the other side inside the base, and has a portion fixed to the base and the other portion disposed to be movable inside the base; an auto focusing (AF) drive unit that moves the lens unit forward or rearward; and first and second optical image stabilizing (OIS) drive units that move the optical path changing unit in a tiltable posture.

A stable single-carrier optical spring, comprising a pair of dielectric mirrors, each having a dielectric coating, and positioned to form a standing wave from an incident optic field. The dielectric coating has a plurality of layers, where at least the first layer is sized to be an odd multiple of half a wavelength of the laser beam, to feature an opposite-sign photo-thermal effect due to the detailed interaction of the optical field with the coating. This results in an opposite-sign photo-thermal effect at the optical spring frequency. The dampening effect is large enough to stabilize the radiation pressure based optical spring, resulting in a statically and dynamically stable optical spring. As a result this coating allows stable locking of a cavity with a single laser frequency using radiation pressure feedback.

A support device for an optical apparatus is disclosed. The support device includes first and second support elements. The support device also includes first and second flexure bearings. The first flexure bearing and the second flexure bearing each connect the first support element and the second support element to one another in a thermally conductive manner and hold the first support element in a manner movable in at least one first direction relative to the second support element. Spring forces generated by the first flexure bearing and the second flexure bearing partly or completely cancel one another out in the case of a movement of the first support element relative to the second support element in the first direction.

A beam transformer for transforming an input laser beam into a transformed laser beam for use in laser systems for line illumination of an object includes a transparent planar optical element that has a front surface and a back surface, which extend substantially parallel to one another. The optical element has an entrance area and an exit area, and a plurality of reflective surfaces for beam deflection. The beam transformer further includes a cooling device provided at least on the front surface or the back surface of the optical element.

An optical device for a vehicle includes an optical sensor module for detecting light that propagates through a light transmitting member; and a correction optical system that includes at least one optical member for allowing the light that propagates between the light transmitting member and the optical sensor module to be refracted in a direction different from a direction refracted by the light transmitting member.
