With Clamp Or Grip Patents (Class 359/818)
  • Patent number: 5642235
    Abstract: A lens having radially extending members provided with convex engaging projections is positioned and secured in a lens supporting sleeve having L-shaped openings with recessed engaging grooves. The radially extending members are positioned with respect to a reference surface of the sleeve, and subsequently elastically deform circumferentially extending clamping arms of the sleeve as they are rotated into clamping portions of the L-shaped openings. The convex engaging projections are then snapped into the engaging grooves, holding the lens in position.

  • Patent number: 5621566
    Abstract: The invention relates to a telescope mounting for a telescope. The telescope mounting is attached on an arm-band. The arm-band could include a watch. The telescope mounting ensures a stable support for the telescope. The length of the telescope should not be longer than 15 cm, preferably 6-7 cm so that the telescope will not be a burden on the arm of the telescope wearer. The diameter of the telescope is no larger than 1.5 cm. The telescope and telescope mounting could be releasable from the arm-band. A slip-on lens could be attached at the front of the telescope.

  • Patent number: 5574600
    Abstract: A light assembly for a track lighting system includes a housing having releasable upper and lower parts. The lower housing part includes a shell and a baffle mounted in the shell. The baffle forms a light-emitting passage and defines a lens seat for receiving a lens that extends across the passage. The baffle carries spring clips which perform the dual function of non-releasably securing the baffle to the shell and retaining the lens on the lens seat.

  • Patent number: 5563740
    Abstract: A vise like device that has a pair of oppositely disposed jaws is disclosed. This vise is used to true the roundness of camera lenses. The jaws form arcs of a circle that corresponds to the size of the lens being repaired. The jaws are threaded to protect the threads on the frame. Once the lens frame is secure on the jaws, the vise is slowly opened, pulling the frame around the jaws until the correct diameter is reached and the frame is round. This procedure saves time because the frame becomes true automatically as the vise is opened. Thus, there is no need to continuously check the roundness against a standard as the process continues. Moreover, this process is more forgiving because the frame is gradually and gently trued up. This gradual process also eliminates the need to remove any over correction to the lens shape. Finally, once the lens had be trued, filters and other accessories can again be attached to the lens.

  • Patent number: 5530547
    Abstract: The present invention is directed to an apparatus for aligning optical elements and a method used to test aspheric components using a conventional interferometer. The apparatus comprises an optical mount having a base and a mount plate used for adjustably mounting an optical element. The mount plate is adjustable relative to the base and includes an assembly surface and several side surfaces. The base is attachable to a bench, table, rail, or the like. An optical element, such as a pre-aligned alignment CGH, is positioned within a first frame, which in turn is releasably coupled to the mount plate. The interferometer generates a spherical test beam which is diffracted by the reflective alignment CGH to create an interferogram. The mount plate is adjusted relative to the base to diffract the test beam onto itself, thus producing null interference fringes.

  • Patent number: 5523893
    Abstract: An optical mounting system is configured so as to locate a 360.degree. shoulder all around the optical element periphery in both the object and image sides of the optical element. The shoulder allows expansion or contraction of the optical element both in the thickness direction of the optical element and in the direction normal to the optical axis when installed in the mounting assembly. Three small metal clips are used to maintain centering of the optics, the thermal expansion and contraction of these clips being coordinated with the clip geometry so that the optical material remains centered without induced stress or free play at either room temperature or at the operating temperature.

  • Patent number: 5486954
    Abstract: An optical device comprises an optical lens and a mounting assembly for securing the optical lens to a support surface. The optical lens has a longitudinal axis and has first and second projections; the mounting assembly includes a clamp member which has a clamp surface and depresses the optical lens downwardly through contact of the clamp surface with the optical lens so as to mount the optical lens on the support surface. The clamp member is formed, on the clamp surface, with first and second holes engageable with the first and second projections of the optical lens, respectively; the second hole is an elongated opening extending in the longitudinal direction of the optical lens.

  • Patent number: 5467229
    Abstract: There is disclosed an adjustable collimator assembly which utilizes a lens barrel member and a housing member which holds a laser diode at a fixed position. A portion of one of these members are received within a portion of the other member. These two members have a coacting member to provide a relative movement between them for adjusting the lens barrel member relative to the laser diode. The potion of the other member which receives the one member has an integral gripping means for gripping the one member to fix the position of the members relative to each other in order to fix the position of the lens barrel relative to the laser diode.

  • Patent number: 5325232
    Abstract: A protection device for a lens used in a scanning apparatus for imaging data on photographic film, comprises a plate and having a finger gripping portion, a member slidably retained in the plate, a glass piece removably carried by the member, and a biasing member operatively associated with the member for selectively permitting secure holding of the glass piece on the member and easy removal of the glass piece from the member. The plate is provided with a biasing device for securely retaining the member in a desired location such that the glass piece is in a predetermined lens protecting position. A switch is associated with the plate such that the switch is moved to an open position upon movement of the member away from the plate. The biasing member is a pivotally mounted spring configured to hold the glass piece in a desired location on the member and has V-shaped portions to engage portions of the member for positive locking of the spring in the member.
