An optical isolator 13 is inserted between the first optical fiber 12 and the second optical fiber 14. An optical fiber that readily generates back-scattering is used for the first optical fiber 12. As light that has back-scattered in the first optical fiber 12 returns to the light source 11, and by constituting a long resonator, the line width of the output light can be reduced.

The prism assembly is located along an optical path between the objective optic and the eyepiece. The prism assembly comprises a first prism and a second prism. The prism assembly allows the user to digitally record images corresponding to a scene or subject being viewed by the user. Both still images and video images may be digitally recorded. The prism assembly inverts the light traveling along the optical path so that the orientation of the image being viewed is consistent with the actual orientation of the scene or subject. The prism assembly allows the optical device to be shorter and more compact for a given magnitude of magnification.

    Abstract: A virtual displaying device used on a telescopic sight includes a sleeve sleeved around an eyepiece portion of the telescopic sight, a virtual assembly and a fixing portion for fixing the sleeve and the virtual assembly to the eyepiece portion. The virtual assembly includes a housing, a virtual member and a displaying screen both received in the housing. Light emitted from the displaying screen passes through the virtual member to be zoomed, shifted and then projected, together with light of the eyepiece, near distance of eye relief of the telescopic sight so that a shooter can simultaneously and clearly see both the target inside the eyepiece and contents displayed on the displaying screen. The present structure above can allow the shooter o obtain important shooting information while aiming at a target and greatly improve the efficiency of the telescopic sight.

    Abstract: A multiple cavity laser system includes: a controller configured to operate the system as well as a plurality of laser cavities, each of the laser cavities having an output end wherein, when activated by the controller, an output laser beam is emitted from the output end of each of the laser cavities. The output laser beams when activated are directed, either directly or indirectly, to a rotating mirror. The rotating mirror is operatively connected to the controller and a servo motor. The servo motor, under direction of the controller, redirects the output laser beams along a common optical axis and the output laser beams of the plurality of laser cavities are combined along the common optical axis.

    Abstract: A two-dimensional light deflector includes first and second deflectors that deflects a light beam, and a fixing member directly fixing both the first and second deflectors. The first deflector includes a light radiating portion, supported oscillatably around a first axis, to radiate the light beam toward the first axis along a first plane perpendicular to the first axis. The second deflector includes an oscillatable reflecting face that reflects the light beam. The reflecting face is inclined by 45 degrees to the first axis and a second axis coincident with a principal ray of the light beam from the radiating portion. The reflecting face is oscillatably supported around a third axis passing through an intersection of the first and second axes and perpendicular to both the first and second axes.

  • Publication number: 20190072760
    Abstract: There is provided a lens device that prevents dust from entering a space in which a movable lens is moved. A movable lens is moved in the direction of an optical axis. A holding member, which extends in the direction of the optical axis, is formed at an end portion of the movable lens. A magnet is fixed to an end portion of the holding member. A hall IC is disposed in a closed storage space at a position facing the magnet. A signal, which corresponds to the position of the magnet in the direction of the optical axis, is output from the hall IC. Since the hall IC is disposed in the storage space closed by a storage box, the entry of dust, which is caused by the hall IC, into a space in which the movable lens is moved is prevented.
