Reticle Patents (Class 33/297)
  • Patent number: 11976901
    Abstract: A passively and naturally illuminated optical reflex sighting system for a firearm in one embodiment includes a housing configured for detachable coupling to the firearm and comprising a plurality of light collection and transmission windows, an optical lens supported by the housing, a fiber optic element, and a light-transmissible cover enclosing the fiber optic element. The cover and fiber optic element are in visual communication with the housing windows which collect and transmit ambient light to the fiber optic element through the cover. The fiber optic element may be disposed inside and protected by the cover which may be clear. In operation, the fiber optic element absorbs ambient light and generates a reticle on the lens for aiming the firearm. A red or other colored dot reticle may be projected on the lens in some embodiments. No onboard artificial light is used to illuminate the fiber optic element.

  • Patent number: 7397252
    Abstract: A method for accurately measuring feature sizes and quantifying the beam spot size in a CDSEM at real time is provided. The inventive method is based on a scanning microscope and it works on both conductive and non-conductive features. The measurement of conductive feature includes first providing a conductive feature on a surface of a substrate (the substrate maybe an insulator, a semiconductor or a material stack thereof). The conductive feature is then connected to ground and thereafter an electron beam probe raster scans the sample. When the electron beam probe hits the conductive feature the spot will have a negative potential. The potential difference between the spot and the ground will induce an electrical current flow. When the electrical beam is off the conductive feature, there will be no current flow. Therefore, by measuring the current response to the location of the beam spot, the dimension of the conductive feature can be derived.

  • Patent number: 6745484
    Abstract: A positional accuracy measurement pattern is formed such that the position of an edge portion required to have high positional accuracy in a device pattern and the position of the pattern center of the positional accuracy measurement pattern are arranged on the same straight line in accordance with a direction in which the high positional accuracy is necessary. On the basis of the pattern center of the positional accuracy measurement pattern and the difference between the measurement value and the design value of the pattern dimension, the positional accuracy (the difference between the measurement value and the design value) of an edge portion of the device pattern is calculated.

  • Patent number: 6324767
    Abstract: A level formed of a flat card that has a series of register marks that are printed on it. The register marks are designed to fit square on the rectangular card. The primary marks are positioned at the two ends of the card. When looking at the register marks, the user can see any angular displacement between them. This angular displacement indicates an out of level condition. If the marks are viewed as being completely horizontal, the card is level. To use the device, simple stand the card up on the surface to be leveled. The angular displacement of the register marks instantly show whether the surface that the card is resting on is level. In this way, just about anything can be tested for level. The device can also be placed on walls or other objects to draw level lines or reference marks. It is also useful as a template for tracing or drawing straight lines for sewing or other activities.

  • Patent number: 5065520
    Abstract: The present invention discloses a reticule device for a fire sighting scope. According to the reticule device of the present invention, it is possible to lighten brightly the entire surface of a scale facing an eyepiece by illuminating light thereto. A light source and a reflection frame are mounted at each prescribed position and further a conventional crossed scale is incorporated into the device as it stands. Furthermore, since a glass plate is not employed in the scale, dust etc. which might adhere on the scale can easily be cleaned or swept off.

  • Patent number: 5025564
    Abstract: A viewing and sighting apparatus is disclosed in its preferred form utilizing a self-luminous lighting material marked on and within clear see-through lenses and may be provided with an electronically lit light source. The sighting device is characterized by a see-through tubular structure with a front clear lens having a cross-like image marked through its center and a rear clear lens having a circle-like image marked in its center. This sighting device is affixed with a means of adjusting the position of the rear circle image in its relationship to the center of the front cross and a means to mount on various weapons of use. The viewing and sighting apparatus may be used to isolate a target area and aim and direct projectile impace to a specific target within the isolated target area and may be further used in darkened conditions.

  • Patent number: 4907882
    Abstract: The surveying instrument contains a component part (1) for the optical imaging of a target and a camera (2) for the electronic acquisition of the image produced in the optical instrument part. A reference mark (20) is located in the optical part (1) of the instrument, and this is outside that region of this instrument part through which the optical axis passes. The image of the target is projected into the region located within the reference mark. Connected to the camera is a circuit arrangement which can detect both the effective center of the image of the reference mark and the effective center of the image of the target and which can determine not only the length, but also the direction of the distance between the two effective centers. The surveying of an object or a region can be carried out automatically by means of this instrument.

  • Patent number: 4395096
    Abstract: A telescopic sight for a rifle or an optical instrument is described having an improved reticle centering mount apparatus. A reticle centering sleeve is provided around a reticle mounting ring mounted within an outer housing tube containing erector lenses supported within an inner lens holder tube in axial alignment along an optical axis. The reticle centering sleeve has a longitudinal cross-section of tapered shape which is wedged between the housing tube and the mounting ring to center the sight point of the reticle on the optical axis. When the erector lenses are longitudinally adjusted within the lens tube to change the magnification of the telescopic sight, the reticle sight point is maintained centered on the image transmitted through such telescopic sight by the centering sleeve.

  • Patent number: 4359282
    Abstract: A method and apparatus for measuring vertical surface variations of a specimen is disclosed wherein the specimen is mounted in movable relation to an objective lens assembly, a reticule being arranged at a focal plane of the objective lens assembly, movement between the objective assembly and the specimen necessary for maintaining the reticule in focus upon different surface portions of the specimen providing an indication of vertical spacing between the surface portions. Another embodiment of the invention contemplates a three-dimensional reticule arranged at or adjacent a focal plane of an objective lens assembly for simultaneously focusing portions of the reticule upon different surface portions of the specimen, the reticule being adapted to provide an indication that the vertical spacing between the different surface portions of the specimen is within acceptable limits.
