Abstract

A holographic sight comprises a unitary optical component carrier. The unitary optical component carrier may comprise a body with a first receptacle configured to receive a laser diode, a second receptacle configured to receive a mirror, a third receptacle configured to receive a collimating optic, a fourth receptacle configured to receive a grating, and a fifth receptacle configured to receive an image hologram. A laser diode may be received within opposing walls formed by the first receptacle. A mirror may be received in, and abut one or more surfaces of the second receptacle. A collimating optic may be received in, and abut one or more surfaces of the third receptacle. A grating may be received in, and abut one or more surfaces of the fourth receptacle. A hologram image may be received in, and abut one or more surfaces of the fifth receptacle.
