A lens attachment module is configured for coupling with a zoom module of a finite conjugate optical assembly. The lens attachment module includes a lens assembly that has a positive focal length, and exhibits a pupil size of between 16 and 25 mm and a pupil depth greater than 50 mm.

The present invention is an optical assembly featuring an architecture which allows adjustment of both objective lenses and the electronic sensing assemblies in the optical assembly. Electrical connections in the housings of the various subassemblies allow focusing adjustment by rotational and/or translational movement for increased adjustability.

A modular helmet display system includes at least one helmet shell, binoculars and a display device. The helmet shell includes a mechanical arch fixedly mounted on the front part of the helmet, and the mechanical arch includes at least one first device for attaching the binoculars. In the system, the mechanical arch includes a second device for attaching the display device. The display device may include a posture detection device and an adjustment mechanism. The display system may include a mechanical cover which is mounted in place of the display device, the shape of the cover being adapted so as to hide the upper part of the helmet. A mobile visor can be mounted on the mechanical arch.

Vision apparatus intended to be mounted on the head of a user, including: a night vision device, for forming first virtual images; an offsetting element, for projecting the first virtual images in the field of view of the user; a shutter, such that the offsetting element is between the shutter and the eye of the user, and able to have an open position that allows light to pass and a closed position that blocks light; a switching element with an open position that authorises emission of the first virtual images or the transfer thereof to the offsetting element, and a closed position that blocks the image emission or transfer; and a controlling device controlling the shutter and the switching element according to opening and closing cycles so the shutter is closed during all or a portion of the time during which the switching element is open, and inversely.

The binocular bridge system is configured to couple two night vision monoculars together, effectively providing the user with a binocular night vision system. An example binocular bridge system comprising: a bridge; a first hinged arm that includes an objective alignment ring configured to fit around an objective lens locking ring of a night vision monocular secured to the first hinged arm; and a second hinged arm that includes an objective alignment ring configured to fit around an objective lens locking ring of a night vision monocular secured to the second hinged arm. The hinged arms in conjunction with the objective alignment rings are configured to mechanically collimate the night vision monoculars secured to the first hinged arm and the second hinged arm of the binocular bridge system.

The invention concerns an augmented vision system (1) comprising: a displaying device (3) comprising: a fixing element (31) for coupling the displaying device (3) to a head-mountable component (90) configured to be positioned in front of a 5 face (102) of a user (100), and a display body (32) being coupled to said fixing element (31) by means of a pivoting link (321, 322, 323) providing a rotation of the display body with respect to the fixing element around a rotational axis (38); the display body (32) comprising 10 a display (33) configured to display thermal data and/or images provided by a thermal sensing device (2); and a first surface portion (325) configured to enter in contact with a forehead of a user, when said head-mountable component (90) is positioned in front of the face of the user, so as to rotate the display 15 body (32) to a predefined angular positioning (381) around the rotational axis (38).

Increasing transparency of one or more micro-displays. A method includes attaching a transparent cover to at least a portion of a semiconductor wafer. The at least a portion of the semiconductor wafer includes the one or more micro-displays. The one or more micro-displays include one or more active silicon areas. The method further includes, after the transparent cover has been attached to the at least a portion of the semiconductor wafer, removing silicon between one or more of the active silicon areas.

A modular finite conjugate zoom lens assembly with five lens groups each including a doublet, wherein two or three movable lens groups are disposed between a pair of static lens groups.

A telescopic sight for detachably connecting a night vision device includes a first external barrel, a regulation element, a first lens module and a transmission module. The first external barrel includes at least one opening, and an end of the first external barrel is configured for detachably connecting the night vision device. The regulation element is disposed on the first external barrel. The first lens module is located at an inner side of the first external barrel. The transmission module is connected between the regulation element and the first lens module via the at least one opening. When the regulation element is driven by an external force, the regulation element drives the transmission module move along an optical axis of the telescopic sight, such that the transmission module drives the first lens module moves along the optical axis to regulate focal length of the telescopic sight.

A rear adapter module for a finite conjugate optical assembly and camera is configured to couple with a core zoom module. A lens assembly of the rear adapter module includes three or more lens elements and has a positive focal length. The lens assembly exhibits a pupil size of between 16 and 25 mm and a pupil depth greater than 50 mm.
