Abstract
Purpose: The purpose of this study is developing the dot sight with a $2{\times}$ magnification. Methods: To magnify the target when we see the far through the non-magnified dot sight, we develop the new optical device which is detachable to the non-magnified dot sight. A new optical device is designed to facilitate the transition of an existing non-magnification ($1{\times}$) dot sight to the $2{\times}$ magnification dot sight. Results: We could design and fabricate the $2{\times}$ afocal optical system which is detachable to the non-magnified dot sight and be composed by a pair of doublet. When the system developed in this study was used, we could aim the external target by twice magnification, so we could further improve the accuracy of aim. Conclusions: We could design and manufacture the $2{\times}$ afocal optical system which can be detachable to the non-magnified dot sight. With the results, we could aim the external target by twice magnification, so we could further improve the accuracy of aim.
