An apparatus including a camera optical element and a tactile indicator associated with the camera optical element for indicating a property of the camera optical element.

A fiber inspection system for inspecting optical-fiber endfaces of a multiple-fiber connector is provided that includes a housing structure, a mating interface fixed relative to the housing structure for interfacing with the multiple-fiber connector, and an imaging assembly. The imaging assembly is enclosed in the housing structure and defines an inspection plane and an image plane, at least a plurality of the optical-fiber endfaces being disposed on the inspection plane, to within a focusing range, when the multiple-fiber connector is mated to the mating interface. The imaging assembly also defines an imaging axis between an inspection point on the inspection plane and a detection point on the image plane, and includes an alignment module disposed between the inspection plane and the image plane and controllable to move the inspection point across the inspection plane for selectively inspecting one or more of the optical-fiber endfaces.

A lens alignment system and method is disclosed. The disclosed system/method integrates one or more lens retaining members/tubes (LRM/LRT) and focal length spacers (FLS) each comprising a metallic material product (MMP) specifically manufactured to have a thermal expansion coefficient (TEC) in a predetermined range via selection of the individual MMP materials and an associated MMP manufacturing process providing for controlled TEC. This controlled LRM/LRT TEC enables a plurality of optical lenses (POL) fixed along a common optical axis (COA) by the LRM/LRT to maintain precise interspatial alignment characteristics that ensure consistent and/or controlled series focal length (SFL) within the POL to generate a thermally neutral optical system (TNOS). Integration of the POL using this LRM/LRT/FLS lens alignment system reduces the overall TNOS implementation cost, reduces the overall TNOS mass, reduces TNOS parts component count, and increases the reliability of the overall optical system.

A device comprising at least two body sections is disclosed. The first body section comprises a movable imaging unit and a magnet rigidly fixed to the imaging unit, and the second body section comprising an optical unit with a magnet rigidly fixed to the optical unit. The body sections are in a movable connection with each other, and the device is operable in at least two modes. In the first mode, the imaging unit and the optical unit are fixed in a set relative position due to magnetic interaction between the magnets. In the second mode, the imaging unit is positioned away from the optical unit.

An adjustable dual-lens device for 3D stereoscopic surgical microscopes has an outer casing, an image set, and an adjusting set. The image set is mounted in the outer casing and has two lenses. The lenses are pivotally mounted in the outer casing at a spaced interval. The adjusting set is mounted in the outer casing and has two adjusting units. Each adjusting unit has a driving motor, a cam, and a limiting element. The driving motor is mounted in the outer casing adjacent to one of the lenses and has a driving shaft. The cam is eccentrically mounted around the driving shaft and is pressed against the lens that is adjacent to the driving motor. The limiting element is connected to the outer casing and the corresponding lens to enable the corresponding lens to press against the cam.

A display module includes a first filter layer, a light-emitting layer, a second filter layer, a photosensitive element, and a driving assembly. The light-emitting layer is disposed between the first filter layer and the second filter layer, the second filter layer is disposed between the light-emitting layer and the photosensitive element, and the second filter layer and the photosensitive element are opposite each other. The driving assembly drives the second filter layer to rotate, so that the second filter layer has a first state and a second state. In the first state, the first filter layer and the second filter layer constitute an ambient-light filter structure; in the second state, the first filter layer and the second filter layer constitute an ambient-light light transmission structure. A first light sensing amount of the photosensitive element is smaller than a second light sensing amount of the photosensitive element.

In a spectroscopic module, a light shielding member is disposed between a plurality of bandpass filters and a light detector. The light shielding member includes a plurality of wall portions. The plurality of wall portions are arranged along an X direction with a light passage opening interposed therebetween, each of a plurality of optical paths from the plurality of bandpass filters to a plurality of light receiving regions passing through the light passage opening. A first wall portion and a second wall portion adjacent to each other among the plurality of wall portions are in contact with the bandpass filter, the bandpass filter corresponding to the light passage opening between the first wall portion and the second wall portion. A width in a Y direction of the light passage opening is larger than a width in the Y direction of the bandpass filter.

A lens barrel includes a lens drive ring actuated to drive a lens group along an optical axis, a driving direction detector detecting a driving direction of the lens drive ring, an actuator actuating the lens drive ring, a power transmission mechanism transmitting a driving force of the actuator to the lens drive ring, a manual operation member to manually move the lens drive ring, and a lens-driving controller controlling the actuator to drive the lens drive ring to move the movable lens group. When the lens drive ring is driven, the lens-driving controller controls a driving output of the actuator according to whether or not a first driving direction of the lens drive ring detected immediately before the lens drive ring is driven and a currently-detected second driving direction of the lens drive ring are mutually identical.

A digital video camera, including a heat management system, which includes at least one inlet and at least one outlet in the housing to enable air to flow through the housing. The heat management system also includes a first heat sink thermally connected to an image sensor(s), and a second heat sink thermally connected to a data processing unit(s), and a centrifugal fan. The centrifugal fan is configured to draw air into the front of the fan in an axial direction and push air radially out in a sideways direction, whereby air travels through the inlet(s) over the first heat sink and then over the second heat sink to the outlet(s).
