Abstract
A combined reflex/telescopic sight that includes a telescopic optical element train and a view window, offset from the optical element train. A transition assembly is positioned to receive light from the optical element train and the view window and has an image display, a collimating lens-set positioned to transmit light to the image display and a luminous reticle. This assembly may be placed in a first mode wherein light from the optical train travels through the collimating lenses to the image display and light from the view window is blocked. In a second mode light from the optical train is blocked and light from the luminous reticle travels through the collimating lens set and is combined with light from the view window and a resulting combined image appears at the image display. Finally an actuation assembly is adapted to permit a user to switch the transition assembly between modes.
