提出設計一款60mm口徑六十倍的單孔式手持望遠鏡，在望遠鏡系統中可分為物鏡系統及目鏡系統，將兩系統分開做設計，設計完成後再將兩系統做結合成望遠鏡系統，物鏡系統由最大入射角度為0.55度半視角，焦距為350 mm，入瞳口徑為60 mm，目鏡系統由最大出射半視角角度為29.941度，焦距為5.833333 mm，出瞳為1 mm，良視距離為14.695257 mm，稜鏡的使用也利於人眼做觀測，再利用幾何光學關係求得所需的稜鏡折射率，將兩系統分別對波前像差、光學畸變、橫向色差，相對照度進行分析及校正是否達要設計要求，兩系統分別設計完成後再將兩系統做結合成望遠鏡系統其放大倍率為60 X，再進行一次分析確認完成後的成像品質是否達到要求，最後設計完成後再進行公差分析確保其設計能夠量產化，設計即完成。

I propose designing a 60 mm single hole telescope with the capability of 60X magnification power. The telescope system consitsts of a object system and a eyepiece system. Both systems are to be designed separately and assembled together afterwards. The maximum incident angle, focal length, entrance pupil diameter of the object system is 0.55 degree a half of FOV, 350 mm, and 60 mm respectively. The maximum exit half angle of view, focal length, exit pupil diameter, and eye relief, and of the eyepiece system are 29.941 degree, 5.833333 mm, 1 mm, and 14.695257 mm respectively. The usage of prisms makes observation via human eyes easier. By using geometric optics to obtain the required refractive index of prism, then analyzing and calibrating the wavefront error, optical distrotion,lateral color and relative illumination of to create both systems, the systems are then to be combined to create the telescope capable of 60X magnification. Afterwards, determine whether the image quality of the final product fits the standards via analyzation.
