The present disclosure is generally directed to a holder that can be used to couple to and optically align an optical component with, for instance, an associated light path to launch or receive optical channel wavelengths along the same. The holder preferably includes a receptacle to couple to the optical component and a mounting section enables the holder to be securely coupled to a substrate in a manner that minimizes or otherwise reduces introducing component shift and resulting optical misalignment.

This disclosure describes an afocal attachment that allows for alteration of received electromagnetic radiation (or “light”) prior to entry into the telescope. For example, a rifle scope may have a base magnification of 2×, and the afocal attachment may allow magnification of a received image at levels ranging from 2× to 4×. In this example, the entire telescope system with the afocal attachment installed will have an overall magnification of 4× to 8×. In another example, the magnification of the telescope can be increased, transforming a telescope with a 4× magnification into a telescope with a higher effective magnification. In some instances the afocal attachment's optical axis can be configured to permit independent adjustment, allowing for easy removal and reinstallation of the afocal attachment without a need to re-adjust the telescope itself.

One example includes an optical port-shuffling module. The module includes a plurality of inputs to receive a respective plurality of optical signals. The module also includes a plurality of outputs to provide the respective plurality of optical signals from the optical port-shuffling module. The module further includes a plurality of total-internal-reflection (TIR) mirrors arranged in optical paths of at least a portion of the plurality of optical signals to reflect the at least a portion of the plurality of optical signals to at least a portion of the plurality of outputs to shuffle the plurality of optical signals between the plurality of inputs and the plurality of outputs.

An adjustable zero-stop turret assembly for an optical firearm scope, the turret assembly defining an axis and including: a turret housing with a cavity to receive a head portion of a main turret screw and including a wall portion defining an opening; a rotatable zero-stop element carrier including a base portion, an upper portion and a first zero-stop element coupled to the base portion; an adjustable set screw adjacent the opening; a second zero-stop element receiving the screw, a first portion of the second zero-stop element positioned within the opening, and a second portion of the second zero-stop element projecting outside the opening and into the turret-housing cavity. The second zero-stop element travels axially along the screw from a first position to a second position. In the second position, portions of the first zero-stop element and the second zero-stop element reside in a common plane perpendicular to the axis.

An adjustment dial assembly for a sealed system includes a knob having a flanged head and a body, wherein the body is dimensioned to extend through an opening in a housing wall, wherein the flanged head is dimensioned to interface with the housing wall. The body includes a seal detent disposed below of the flanged head for receiving a seal, a fastener interface disposed below the seal detent configured to interface with a fastener for retaining a movement regulation assembly and the knob to the housing wall, and a drive screw opening disposed within the body and configured to receive a drive screw such that the drive screw can be axially moved relative to the knob when the knob is rotated and the drive screw is rotationally fixed.

An imaging apparatus includes a substrate including an imaging element, one or two attachment portions that attach the substrate by screwing and are capable of inclining a board surface of the substrate, by screwing in a screw, relative to a plane perpendicular to an optical axis of an optical system that forms an optical image on the imaging element; and one or more supports configured to abut the substrate from an opposite direction to a screwing direction of the attachment portion at any position, on the substrate, that rotates in the screwing direction of the attachment portion when the board surface is inclined by screwing. As a result, an imaging apparatus that allows an imaging element to be installed at a desired position and orientation while reducing the size of the substrate is provided.

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.

A system includes a compound flexure having a frame, a flexure, and a post flexure. The frame has an axis, and the flexure is located within the frame. The flexure is movable relative to the frame, and the frame and the flexure form at least part of a monolithic structure. The post flexure extends along the axis and engages the flexure. The system also includes a device coupled to the flexure and configured to move with the flexure relative to the frame. The system further includes an actuator coupled to the flexure and configured to move the flexure and the device relative to the frame.

The present disclosure describes a device (10) for the acquisition of optical information, in one embodiment including an external case (11) and, within the case (11), an optical module (20) including an optical focusing group (21) having an optical axis (X). The device (10) may further include, within the case (11), a mechanical actuator (50) associated with the optical focusing group (21) and configured in such a way as to move the optical focusing group (21) along the optical axis (X). The mechanical actuator (50) may include a gripping member (51) of the optical focusing group (21) arranged externally with respect to the optical module (20) and associated with the optical focusing group (21) on opposite sides with respect to the optical axis (X). The gripping member (51) can be moved along a direction parallel to the optical axis (X) such as by way of a control member (70) extending coaxially to the optical axis (X) and operatable in rotation around the optical axis (X) from the outside of the case (11).
