  • Patent number: 9116415
    Abstract: A pop up prism camera (10) having a pop up prism lens assembly (11). A first lens assembly (14), a second lens assembly (18), and a prism assembly (21) are moved in relationship to a camera housing (12) controlled by a cam tube (20). The prism assembly (21) projects outside the camera housing (12) when the pop up prism camera (10) is in an operational configuration. A prism (100) of the prism assembly (21) redirects an optical path (48). A non-angled portion (44) of a first cam groove (30) causes the prism assembly (21) to remain fixed relative to the camera housing (12) while continued rotation of the cam tube (20) allows the first lens assembly (14) and the second lens assembly (18) to continue to move to accomplish a lens zoom function.

  • Publication number: 20140168765
    Abstract: An optical device for viewing distant objects. The device includes an objective system and at least one ocular and achieves a magnifying power of greater than 0.6 mm?1 times the entrance pupil diameter in millimeters with an exit pupil of at least 2 mm Images from the objective system are detected by a sensor, processed and recorded. The images are displayed on a display which is observed by the user through one or more oculars. The optical device works well at low light levels. The device also has a slide mechanism for adjusting the interpupillary distance between the oculars.

  • Patent number: 6373640
    Abstract: Optical systems for use in digital cameras are provided. The systems can be switched between three optical paths (1,2,3): a first path (1) for through-the-lens (TTL) viewing; a second path (2) for recalling previously taken pictures from a microdisplay (16); and a third path (3) in which pictures are taken using an electronic sensor (15), e.g., a CMOS sensor. The optical systems employ a zoom objective lens unit (10), e.g., a 3:1 zoom, an erector lens unit (12), and an eye lens unit (13). They can also employ an image size adjusting lens unit (11) for equalizing the TTL and recalled images presented to the user.
