A system and method for activating an optic for a gun. A magnetic field from a magnet proximate the optic is detected. Power to the optic is turned off from a battery of the optic in response to detecting the magnetic field. Power to the optic is turned on from a battery in response to not detecting the magnetic field.

A holographic, single-unit, augmented sight has a housing containing a see-through holographic eyepiece; at least one of a visible light digital camera and an LWIR digital camera; a display to display an image from the camera(s); a shutter presenting the display; a red dot fiber-coupled LED reticle assembly using a spherical ball configuration sandwiched between two matching seats which are compressed together to contain the spherical ball configuration optical position; and a lever attached to the spherical ball configuration to rotate the ball by moving the lever up/down, left/right to adjust windage and elevation; a lower coupling prism presenting the reticle of the reticle assembly.

An intensity adapting optical aiming system that automatically adjusts the intensity of the reticle to adapt to the light condition of the external light. The aiming system may be mounted to a weapon and the external light may be a weapon mounted light. The aiming system may include an illuminateable reticle and a light connector for transmitting light from the external light to the reticle.

A sight includes a housing, a rangefinder assembly, a display screen provided in the housing and electrically connected to the rangefinder assembly, an objective lens set, an image inverter set, a reticle set, and an eyepiece set provided in the housing and sequentially arranged from an object side to an eye side, where the reticle set includes a first prism and a second prism cemented to each other, a reflective film is provided on a first cemented plane of the first prism and the second prism; the first prism has a first plane provided on an imaging plane; the second prism has a second plane perpendicular to the first plane; the first plane is provided with a reticle pattern; a light-emitting plane of the display screen is attached to the second plane; and the reflective film is configured to reflect light from the display screen to the eye side.

A dot sight includes a sight mount, a sight frame, a light source member, a collimator lens set, a reflector, and a beam splitter prism, where a first chamber is formed in the sight mount; the sight frame is provided at a circumferential side of the sight mount close to an eye side; a second chamber, and a through opening communicating the second chamber and the first changer are formed in the sight frame; the light source member is provided at an end of the first chamber close to an object side, and configured to emit light to the eye side; the collimator lens set is provided in the first chamber; the reflector is provided in the first chamber, and corresponding to the through opening; the beam splitter prism is provided in the second chamber; and an axial position of the light source member is adjustable.

An electro-active lens provides simultaneous focusing at two different optical powers. It does this with a stack of electro-active lens elements aligned along the same optical axis that each focus light in different polarization states (e.g., horizontal and vertical polarization states). If a first and second electro-active lens elements have different optical powers, light in a first polarization state can be focused to one optical power and light in a second polarization state can be focused to a different optical power simultaneously. The electro-active lens can be switched between different single and multiple optical powers. People with presbyopia may use the electro-active lens mounted in eyewear in place of conventional bifocal glasses. The electro-active lens may also be used in a scope to improve target aiming.
