  • Patent number: 11619466
    Abstract: There is provided a dot sight device including a housing being configured to have an open front and an open rear, and a light path connecting a user with a target along a central axis of the light path disposed therein. A dot reticle generating unit generates a plurality of light rays for forming a dot reticle. A reflective mirror reflects the light rays provided from the dot reticle generating unit toward the user to form an image on a target side. A compensating plate is disposed along the light path of the housing together with the reflective mirror and passes through the light rays coming from the target to be directed toward the user. The compensating plate is configured to suppress or minimize one or more movements of the image of the target caused by one or more movements of the dot sight device.

  • Patent number: 10655933
    Abstract: An exemplary dot sight device includes a sight body, an illumination unit, an optical system, first, second and third movement blocks, and first, second and third adjustors. The first, second and third movement blocks are disposed in the sight body. The first adjustor is coupled to the first movement block and operable to cause the first movement block to move thereby causing the illumination unit to be displaced along a first axial direction. The second adjustor is coupled to the second movement block and operable to cause the second movement block to move thereby causing the illumination unit to be displaced along a second axial direction different than the first axial direction. The third adjustor is coupled to the third movement block and operable to cause the third movement block to move thereby causing the illumination unit to be displaced along the second axial direction.
