4results about How to "High focusing precision" patented technology

The utility model relates to the technical field of focusing, in particular to a focusing device for improving focusing precision based on a long lens cone, which comprises a substrate; the fixed lens cone is arranged on the substrate; the fixed lens cone is provided with an axial chute, and one end of the fixed lens cone is provided with a laser light source. The lengthened inner lens cone is movably arranged in the fixed lens cone at a preset gap; a focusing lens is arranged at one end, close to the laser light source, of the lengthened inner lens cone; the driving mechanism is arranged on the base plate; the driving mechanism is connected with the lengthened inner lens cone through the adjusting mechanism and the axial sliding groove and drives the lengthened inner lens cone to move along the axial sliding groove. And the axial deviation angle between the lengthened inner lens cone and the fixed lens cone is reduced along with the increase of the length of the lengthened inner lens cone, so that the focusing precision is improved. The focusing device has the advantages that by lengthening the inner lens cone and simplifying the structures of the lengthened inner lens cone and the fixed lens cone, the stability of the focusing device is remarkably improved, and the problem of light spot shaking is solved.

The utility model relates to a kind of focusing tool, including pedestal, pedestal is plate-like;Supporting plate, supporting plate is set on the board surface of pedestal and extends along the vertical direction of pedestal;At least one adjusting plate, the side wall of adjusting plate is rotatably connected with the side wall of supporting plate by rotating connecting piece, and the axis of rotating connecting piece is perpendicular to the extension direction of adjusting plate;Through hole is opened in the board surface of adjusting plate, and at least one focusing lens barrel, focusing lens barrel is sleeved with through hole.This focusing tool is set along vertical direction extending supporting plate on pedestal, and rotatable adjusting plate is arranged at supporting plate side wall, the controllable adjustment of focusing lens barrel in space angle is realized, so that focusing process has higher flexibility and operability.Adjusting plate uses rotatable connecting structure and is provided with the through hole that can be clamped, and by clamping gap cooperation fastener, stable clamping force can be formed to focusing lens barrel.

The utility model discloses a focusing device and a therapeutic apparatus, and relates to the technical field of focusing devices, the focusing device comprises a first focusing cylinder, the first focusing cylinder is internally provided with a first light path channel; a first lens group and a second lens group are arranged in the first focusing cylinder, the first lens group comprises a plurality of first lenses which are arranged along the optical axis direction and are fixedly connected with the first focusing cylinder, and the second lens group comprises a plurality of second lenses which are arranged along the optical axis direction and are in sliding connection with the first focusing cylinder in the optical axis direction; the first end of the focusing rod extends into the first focusing cylinder and is fixedly connected with the second lens; an operator can adjust the size of a light spot by operating the focusing rod, so that the focusing device has a relatively stable focusing effect, and the focusing cost is reduced; the positioning assembly provides a focusing basis for an operator, and the focusing precision of the focusing equipment is improved; the first focusing cylinder separates the focusing rod from the first light path channel, so that the focusing device has high focusing efficiency and focusing precision.

The utility model relates to a lens, including movable lens and focusing structure, focusing structure includes focusing support, focusing silk mother and focusing screw rod, focusing support fixed connection in movable lens's lens barrel, focusing silk mother sets up on focusing support and its axial parallel movable lens's axial, focusing screw rod is screwed with focusing silk mother and sets up to movable lens's image side extension, the extension tail end of focusing screw rod is connected with the focusing hand wheel for driving its rotation around the own axis. In addition still provide a kind of imaging equipment using above-mentioned lens barrel, imaging chip is located between movable lens and focusing hand wheel. In the utility model, connecting focusing support on movable lens and connecting screw rod mechanism by focusing support, and focusing screw rod sets up to movable lens's image side extension, not only can realize long distance focusing, but also can make the radial dimension of lens smaller;Focusing hand wheel and the lens barrel of lens are relatively separated, more suitable for single-handed operation, and use experience is better.
