Purpose:The purpose of this study is developing the 2.6 × optical scope with a Abbe-Konig prism.
Methods: First, considering the size of the effective aperture and the focal length of the objective lens, we designed an Abbe-Konig prism. Next, we calculated the optical and geometric distances of Abbe-Konig prism designed in thisway. After allocating the focal length of the objective lens and the eyepiece lens so as to satisfy the magnification
and optical effective distance of the entire system by using this calculation result, we completed the entire system
by optimizing this optical system.
Results:We were able to complete the optical scope of about 2.6 × magnification by
designing an objective lens with a focal length of 63.13 mm which was composed of two pieces, an eyepiece
with a focal length of 24.3 mm which was composed of four pieces, and an Abbe-Konig prism with a face length
11.5 mm.
Conclusions:We designed and fabricated an optical scope with 2.6 × magnification employing an
Abbe-Konig prism. Then, this system became the compacted optical system with a barrel diameter of 31 mm,
characterized by an effective aperture of 12.0 mm and an effective optical barrel length of 103 mm and a
resolution of 200 cycles/rad at 50% MTF criterion within the half viewing field angle of 6.42o.
