Abstract:
An apparatus for illuminating and targeting a target, comprising:a light source emitting a beam toward the target; a positive convex-planar lens positioned in the beam that refracts a first portion of the beam along a convergent path to a first focal point and that transmits an unrefracted second portion of the beam; and a negative planar-convex lens positioned in the beam downstream of the positive convex-planar lens and spaced apart from the positive convex-planar lens, the negative planar-convex lens transmitting at least part of the second portion to form a targeting dot on the target, the negative planar-convex lens refracting at least part of the first portion of the beam to form a relatively larger illuminating footprint on the target, the negative planar-convex lens being coupled to a translating mount configured to translate the negative planar-convex lens relative to the positive convex-planar lens.
