  • Patent number: 7061695
    Abstract: An optical system is provided. In order from an object side to an image side, the optical system includes a first lens element having a positive power, a meniscus shape, and an object side surface. The object side surface of the first lens element is convex toward the object side. A second lens element has a negative power, a meniscus shape, and an object side surface. The object side surface of the second lens element is concave toward the object side. A third lens element has a positive power. An aperture stop is positioned on or in front of an object side of the first lens element.

  • Patent number: 6114075
    Abstract: A flash device includes a micro-optic array for concentrating light from the flash lamp on a radiation-absorbing dye carrier, thereby sublimating or vaporizing the dye from the radiation-absorbing dye carrier onto a receiver element, e.g. a glass plate or the like.

  • Patent number: 5934779
    Abstract: A reflector includes one closed end, one open end and highly reflecting curving walls. The walls are symmetrical about at least one axis of symmetry. The walls include a first segment and other segments. The first segment has a curved shape and is located at the closed end of the reflector. The first of segment directs most of the light rays incident on it across the axis of symmetry at crossover points, prior to the rays striking the associated target surface. Most of the light rays striking the walls of the first segment near the closed end of the reflector are having crossover points near the light source. Most of the light rays striking the walls of the first segment progressively further away from the closed end of the reflector are having crossover points located progressively closer to the associated target surface. The other segments direct nearly all of light rays incident on the walls of the other segments towards a portion of the associated surface.

  • Patent number: 5822625
    Abstract: An improved hybrid camera is provided for capturing an image photographically on film and electronically on an electronic sensor in which the image captured by the electronic sensor may be electronically cropped to match the image captured on the film. The camera includes a first lens having multiple focal lengths and a second lens having two selectable focal lengths. The image is focused through the first lens onto the film to capture the image photographically, while the image is focused through the second lens on an electronic sensor to capture at least the image electronically. A controller in the camera selects the focal length of the second lens to maximize the resolution of the portion of the image captured on the electronic sensor which matches the image captured on the film. The image captured on the electronic sensor may be cropped by the controller to match the image captured on the film.
