Figures 1 and 2 are the optical system diagram and the same field of view diagram of a conventional zoom telescope.
The figure shows an example at low magnification, and Figure 3 shows the telescope of the present invention. Fig. 3a shows the optical system diagram of the telescope at high magnification with the variator lens positioned outside the optical axis, and Fig. 3 b to d show the telescope at high magnification. This is a diagram of the optical system of a telescope with the variator lens positioned on the optical axis at magnification, b is the state before focusing, c is the state after moving the objective lens and focusing, and d is the state when the eyepiece is moved.

よう装着したことを特徴とする多段変倍望遠鏡。 In a telescope that changes magnification in multiple stages while always keeping the focal position of the objective lens and the focal position of the eyepiece aligned, a variator lens that changes the focal length of the objective lens is used to change the focal length of the objective lens and the focal position of the objective lens. The variator lens is mounted so that it can freely protrude and retract between the variator lenses, and the objective lens or eyepiece lens is mounted so that it can be moved in the optical axis direction so as to compensate for changes in the focal position of the objective lens before and after the variator lens protrudes and retracts. A multi-stage variable magnification telescope.
