Abstract
A lightweight contact holographic sight includes a housing and a base which form a compartment containing a laser diode, an associated power source, and optical elements including a mirror, an off axis collimator, a reflection grating, and an image hologram of a reticle pattern, wherein the optical elements are arranged within the compartment to direct and fold the laser beam in a substantially generally vertical path. In one aspect of the invention, an elevation and windage adjustment mechanism is provided to rotate the reflection grating about two orthogonal axes to thereby adjust the projected reticle pattern for windage and elevation. In another aspect of the invention a removable battery compartment including a cam surface which is releasably contacted by a cam lever arm pivotally mounted on the sight housing or the base to allow for quick tool-less removal of the compartment for battery replacement.
