Latest Patents
One of Lunt's notable inventions is the neutral white-light filter device. This device achieves a substantially neutral filter across the white-light spectrum by minimizing the wavelength-dependent effects of filtering components and reflective coatings on surfaces. The design captures incoming light using a first prism, directing it toward an interface formed by the optical contact of a second prism. At this interface, the light is partially reflected internally and partially transmitted into the second prism. The reflected light is then directed toward the image surface out of the first prism. The fraction of light transmitted into the second prism is reflected back and redirected toward the incoming beam. The energy directed toward the image plane is controlled by the careful selection of refractive indices in the materials at the contacting interface of the prisms. The second prism includes a retro-reflector element that reflects nearly all light transmitted at the interface back along the optical path of the incoming beam.
