Optical bench

A weapon sight assembly, comprising:

• an optical bench supported in a housing, the optical bench including a reflex sight mounting portion having a first surface for receiving a reticle light source;
• and a first reticle lens mounting arm spaced apart from a second reticle lens mounting arm, the first and second reticle lens mounting arms attached to the reflex sight mounting portion, and the first and second reticle lens mounting arms configured to engage opposite sides of a reticle lens to support the reticle lens in an optical path of the reticle light source, the first and second reticle lens mounting arms being sufficiently resilient to accommodate thermal expansion and contraction of the reticle lens, wherein the first and second reticle lens mounting arms are resilient with multiple degrees of movement;
• the reticle light source received within the housing and attached to the first surface;
• and
• the reticle lens attached to the first and second reticle mounting arms.

• said optical bench further including an aiming laser portion and one or more aiming laser flexures connecting the aiming laser portion to the reflex sight mounting portion, wherein the aiming laser portion is pivotable about said one or more aiming laser flexures for adjusting an angular orientation of the aiming laser portion in relation to the reflex sight mounting portion, said aiming laser portion including at least one laser receptacle receiving a laser emitter and at least one lens receptacle supporting a laser lens assembly in an optical path of the laser emitter;
• the reticle light source received within the housing and attached to the first surface;
• and
• the reticle lens attached to the first and second reticle mounting arms.
