Abstract: A clip-on eyepiece system that enables a single portable digital imager to be used in both handheld and device-mounted applications is disclosed. The system has a clip-on eyepiece assembly that includes an inverting or a non-inverting eyepiece, a clip-on bracket, a T-mount, and a magnet. The digital imager comprises a display, a mounting rail, a Hall-effect sensor, and a processor all configured to dynamically determine which type of eyepiece, if any, is attached, and to dynamically set system parameters to configure the digital imager for use in either a handheld or a mounted mode. A method for setting operational parameters when the user attaches or detaches the clip-on eyepiece assembly is also disclosed.

Abstract: A GPS/compass imager system for a viewing system includes a display head and a GPS/power unit electrically connected by an electrical cable. The GPS/power unit provides a GPS signal and electrical power to the display head. The display head includes a display, an electronic compass, control electronics and a collimating lens. Compass information and GPS information are displayed on the display. The display head is configured to be operably arranged adjacent an objective lens of an image-intensified viewing system. The collimating lens and an objective lens serve to form a display image on the viewing system's image intensifier so that the compass and GPS information, as well as the image-intensified view of the scene, is visible to a viewer over the image-intensified viewing channel.

Abstract: An optical system provides a lens cell having a generally cylindrical lens cell body and an optical lens system therein. The lens cell body has a lens cell central longitudinal axis and a lens cell optical axis, eccentrically offset from the lens cell central longitudinal axis. A sleeve has a generally cylindrical sleeve body, an outer surface with a first longitudinal axis, and an inner surface with a second longitudinal axis, eccentrically offset from the first longitudinal axis. The lens cell is inserted into the sleeve. A housing has a generally cylindrical body into which the sleeve is at least partially inserted. The lens cell and the sleeve are rotated relative to each other and to the housing such that the lens cell optical axis is aligned in a desired location. After the lens cell optical axis is aligned in the desired location, the lens cell is fixedly connected to the sleeve and the sleeve is connected to the housing to prevent rotation of the sleeve relative to the housing.

Abstract: A night vision device comprising a first detector, a beam splitter, a user optical output and a camera. The first detector is configured to detect and transmit a scene image in a first spectral band along a first optical path. The beam splitter is configured to receive the first optical path image; to output, along a second optical path, a first portion of the first optical path image, and to output, along a third optical path, a second portion of the first optical path image. The user optical output is configured to receive and output images traveling along the second optical path. The camera is configured to receive and store images traveling along the third optical path.
