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.

The present invention relates to mounting assemblies for optical devices, including enhanced night vision goggles (ENVG), and more particularly to a multi-adjustable and multi-stowable mount for a single or dual enhanced night vision goggles (ENVG). The mounting assemblies can include a quick release system for detachment of the optical device from the mount.

A projection exposure apparatus for semiconductor lithography includes a component and fixed to a structural part of the apparatus. The component and/or the structural part have/has a stop for bearing against a reference surface at the structural part and/or the component. The stop is movable relative to the component fixed and/or the structural part so that it can be moved away from the reference surface. A method for adjusting a component on a structural part of a projection exposure apparatus includes: securing a stop to the component or the structural part; positioning the component so that the stop comes into mechanical contact with a reference surface at the component or the structural part; fixing the component to the structural part; and moving the stop away from the reference surface.

A laser frame for holding a plurality of optical components includes a first flexure structure for adjustably holding a first one of the optical components, and a first cellular structure for supporting and cooling a second one of the optical components. The first flexure structure and the first cellular structure are each a unitary structure formed by additive manufacturing. Also, a laser frame for holding an optical component includes a passive cooling cellular structure for supporting and cooling the optical component. The passive cooling cellular structure has a non-uniform density, and the laser frame is a unitary structure formed by additive manufacturing.

An adapter may be used to couple an imaging device, such as a smartphone, to an optical device such as a telescope. The adapter may have an optical device mounting feature that mounts the adapter to the optical device, an imaging device mounting feature that mounts the imaging device to the adapter, and a positioning mechanism that adjustably positions the imaging device mounting feature relative to the optical device mounting feature. The optical device mounting feature may have a first arm, a second arm that is movable relative to the first arm to clamp a portion of the optical device between the first arm and the second arm, and a lock that can be actuated to restrict motion of the second arm away from the first arm. The positioning mechanism may be actuatable to move the imaging device, relative to the optical device, along three orthogonal axes.

A low-drift optical mount comprising a first plate, a second plate, at least one drive rod, at least one collet. A first collet may extend through a bore of the second plate and has an inner screw matching the external screw of a first drive rod. The first drive rod may have a contact end with the first plate and a spring pulls the first plate back toward the second plate. The collet may have at least one slot that extends through the own inner thread surface. The slot can relieve the drift performance induced by grease which fills in the thread fit clearance and further improve the position stability of optical mount.

A digital turret having an adjustment selector configured to adjust a main optical axis of a riflescope relative to a bore line of a shooting device. The digital turret may be configured to determine a position of the adjustment selector relative to a zero point of the adjustment selector. The digital turret may be further configured to transmit an electronic signal corresponding to the position of the adjustment selector.

A test fixture for holding and testing portions of an optical device, such as a plurality of cameras of an eyewear device. The test fixture includes a relay lens such that the fixture can be positioned close to a test screen displaying a patterned test image and reducing the size and cost of parts. The test fixture includes one or more lasers configured to easily and quickly align the test fixture. The test fixture includes an actuator for selectively positioning the cameras behind the relay lens to check for image quality.

An optical module includes a housing, an optical component, a first elastic member and a second elastic member. The housing has a first end, a second end and a through hole, wherein the first end is opposite to the second end. The optical component is disposed in the through hole. The optical component has a third end and a fourth end, wherein the third end is opposite to the fourth end, the third end protrudes from the first end, and the fourth end protrudes from the second end. The first elastic member is rotatably disposed on the first end and abuts against the third end. The second elastic member is rotatably disposed on the second end and abuts against the fourth end.
