摘要： A holographic sight comprises a unitary optical component carrier having a plurality of receptacles for receiving optical components. A collimating optic abuts a surface of a first receptacle. A mirror abuts a surface of a second receptacle. A collar is positioned in a third receptacle and a laser diode is positioned within the collar. A first portion of the collar is affixed relative to a first portion of the third receptacle and a second portion of the collar is free to expand anc contract relative to the third receptacle. The laser diode is affixed to the collar proximate the second portion and is free to move relative to the third receptacle with expansion and contraction of the second portion. The laser diode, the mirror, and the collimating optic are positioned relative to each other to create an optical path. The collar expands and contracts in response to changes in temperature to compensate for the unitary optical component carrier expanding and contracting in response to changes in temperature.
