Abstract
A refractive body includes a lens, holder, and aperture particularly suited for use in raster scanners. The refractive body advantageously can be made from resinous materials, such as plastics, but can be formed from any refractive material as may be appropriate. The aperture is formed from portions of the refractive body surrounding the lens and can act to divert excess light from the optical path of the scanner by refraction or reflection.
Claims22
A combined lens and aperture comprising:
- a lens in selective photonic communication with a light source and a target, the lens and the target lying on an optical path;
- at least one surface about the lens that redirects excess light to an absorptive body;
- and
- wherein the combination is part of a raster scanner.
A combined lens and aperture comprising:
- a lens in selective photonic communication with a light source and a target, the lens and the target lying on an optical path;
- at least one surface about the lens that redirects excess light to an absorptive body;
- and
- wherein the body is formed from fused silica.
A refractive body including:
- a lens portion;
- an aperture portion surrounding the lens portion and directing excess light off of an optical path coincidental with a major axis of the lens portion;
- and
- wherein the refractive body is part of a rater scanner.
A refractive body including:
- a lens portion;
- an aperture portion surrounding the lens portion and directing excess light off of an optical path coincidental with a major axis of the lens portion;
- and
- wherein the refractive body comprises fused silica.
A xerographic printing machine including a raster scanner comprising a refractive body, the refractive body itself comprising:
- a lens portion;
- an aperture portion surrounding the lens portion and directing excess light off of an optical path.
