Abstract
Purpose: This study relates to the development of dot-sight device, whose length is reduced, with a prism beam splitter. Methods: We developed a new dot-sight device whose length was reduced by eliminating the optical axis tilt of the doublet reflector to reduce the occurrence of the parallax and by redesigning the doublet reflector to use a prism beam splitter. Results: We could develop the new type dot-sight device having a prism beam splitter and the dot reticle generator and the doublet reflector, of which optical axises showed a T-letter type with the optical axis of the observer's eye. Conclusions: In this study, we designed and developed a new type dot sight employing a prism beam splitter that could be able to further enhance the accuracy of the fire in comparison with the traditional dot sight, thereby reducing the overall optical length of system. The new designed dot sight was able to be reduced 2.2 times on the overall optical length, and could be improved more than three times on the accuracy of shooting in the horizontal direction, than the traditional dot sight.
