There are provided a lens guide device, a lens moving device, and an imaging apparatus that can accurately position a lens frame regardless of an attitude, such as an imaging direction. A first-rail supports a first-rolling-body so as to allow the first-rolling-body to be rollable in a first-direction parallel to an optical-axis of a first-focus-lens. A second-rail supports a second-rolling-body so as to allow the second-rolling-body to be rollable in the first-direction. A biasing-mechanism supports the first-rolling-body so as to allow the first-rolling-body to be movable in the first-direction, and biases the first-rolling-body toward the first-rail. A third-rail is provided in parallel with the second-rail. The third-rail supports the second-rolling-body so as to allow the second-rolling-body to be movable in the first-direction. Since the first-rail and the second-rail are moved and guided in a first direction by the first-rolling-body and the second-rolling-body, a lens frame is not inclined.

The invention relates to an adjustment device (1), comprising at least two linear stages (2, 3), which are arranged next to each other and which are fixedly connected to each other (6) by means of one of the adjustment sections (5) of each of the linear stages such that an adjustment movement of one linear stage can be transferred to the adjacent linear stage, wherein one linear stage is designed to bring about an increase in the distance between the adjustment sections arranged on said linear stage as a result of actuation of the adjustment element and an adjacent linear stage is designed to bring about a decrease in the distance between the adjustment sections arranged on said linear stage as a result of actuation of the adjustment element so that a displacement of the adjustment device can be realized, which displacement corresponds to the sum of the amounts of the changes in the distance between the adjustment sections of the linear stages.

The present teachings provide an image capture device including a bayonet and an integrated sensor and lens assembly (ISLA). The bayonet is connected to a body of the image capture device. The ISLA is connected to the bayonet. All or a portion of the ISLA extends into the body of the image capture device. The ISLA includes a lens assembly having a forward end and a rearward end and an integrated sensor. The integrated sensor is connected to the rearward end of the lens assembly. Fasteners extend through the bayonet into the forward end of the lens assembly to connect the ISLA to the bayonet.

A method of manufacturing a lens including forming a cover blank having cover parts by injecting a thermosetting first resin in a first mold and curing the thermosetting first resin, removing a part or all parts of the first mold, and arranging the cover blank in a second mold. The method further includes forming a lens blank having a light-shielding part between adjacent cover parts by injecting a thermosetting second resin having a greater light absorptance or light reflectance than the thermosetting first resin into the second mold and curing the thermosetting second resin, and obtaining individual lenses by taking out the lens blank from the second mold, and cutting the lens blank at the light-shielding part located between adjacent cover parts to obtain individual lenses each with lateral end surfaces and an upper surface of each of flange parts and lateral side walls covered by the light-shielding part.

An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed portion, a movable portion, a first driving assembly, and a positioning element. The movable portion is movably disposed on the fixed portion and comprises an optical element, wherein the optical element moves in the first direction. The first driving assembly is at least partially disposed on the fixed portion. The positioning element is rotatably disposed on the fixed portion or the movable portion, wherein when the first driving assembly is not activated, the positioning element is used to limit the position of the movable portion relative to the fixed portion to a limit position.

Provided is an attachment system for coupling a mobile computing device to an optic device. The optic device may be, but is not limited to a scope, binoculars or the like. The attachment system operates with attachment devices and mounting device with apertures that provide a means to couple a mobile computing device to the optic device in such a way that the attachment system provides a line-of-sight between a camera of the mobile computing device with the lens of the optic device. This allows the camera of the mobile computing device to capture images and video using the high power zoom functionality of the optic device and the convenience of the mobile computing device.

A fluorescent color wheel includes a substrate, a phosphor layer, and a fan blade structure. The substrate has a front surface, a rear surface opposite to the front surface, and a plurality of through holes communicating the front surface and the rear surface. The phosphor layer is disposed on the front surface. The fan blade structure includes a heat-dissipating plate and a plurality of first fan blades. The heat-dissipating plate has a first surface attached to the rear surface of the substrate. The first fan blades are disposed on the first surface and respectively pass through the through holes to protrude out from the front surface of the substrate.

The disclosure relates to a damping arrangement for vibration damping of an element in an optical system, for example in a microlithographic projection exposure apparatus. A damping arrangement according to the disclosure has an element, a fluid located in a cavity, and at least one channel connected to the cavity. A vibration of the element causes vibration energy of the element to be dissipated by partial displacement of the fluid from the cavity into the at least one channel.

An apparatus includes an eye cover adapted to be removably mounted on a head-worn computer with a see-through computer display and a flexible audio headset mounted to the eye cover. The flexible audio headset is mounted to the eye cover with a magnetic connection.

A lens assembly includes: a first lens including a protrusion; and a second lens disposed adjacent to the first lens and including a recess configured to accommodate at least a portion of the protrusion. The protrusion is spaced apart from the recess in an optical axis direction.
