Patent ID: 7119972

Claim:
An apparatus for reflecting a light beam, comprising: a first wedge comprising a first refracting surface and a second refracting surface; a second wedge comprising a third refracting surface adjacent to the second surface, and a reflecting surface; an optical mount comprising a clamp defining an opening; a first optic holder mounted to the optical mount, the first optic holder comprising a first cylinder with a first outer ledge and a first inner ledge, wherein the first wedge is mounted to the first inner ledge and the first optic holder is received in the opening of the optical mount so the first outer ledge abuts a first side of the optical mount; a second optic holder mounted to the optical mount, the second optic holder comprising a second cylinder with a second outer ledge and a second inner ledge, wherein the second wedge is mounted to the second inner ledge and the second optic holder is received in the opening of the optical mount so the second outer ledge abuts a second side of the optical mount; wherein the light beam refracts at the first refracting surface, refracts at the second refracting surface, travels in air to the third refracting surface, refracts at the third refracting surface, reflects from the reflecting surface, refracts at the third refracting surface, travels in air to the second refracting surface, refracts at the second refracting surface, and refracts at the first refracting surface.
