ABSTRACT:
An apparatus has structure with a reticle oriented approximately parallel to and adjacent an imaginary plane. The structure includes on one side of the plane a portion transmissive to visible radiation, the portion having a surface that is spaced from and angled with respect to the plane, and that faces away from the reticle. A reticle illumination section emits radiation adjacent the surface. According to a different aspect, a method involves: providing a reticle oriented approximately parallel to an imaginary plane and disposed immediately adjacent the plane; providing on one side of the plane a structural portion that is transmissive to visible radiation; forming on the portion a surface spaced from the plane, oriented at an angle to the plane, and oriented to face away from the reticle; and emitting radiation adjacent the surface.
