PURPOSE: A dot sight device including a polarization unit is provided to reduce difference of time by freely designing an angle of a reflector and to prevent an observer from being detected by exposure of rays. CONSTITUTION: A dot sight device including a polarization unit comprises a reflector, a first polarization unit(130), a dot indication generation unit(140), and a second polarization unit(150). The first polarization unit is installed in the front of the reflector, and the second polarization unit is installed in the front of the dot indication generation unit. Rays of the dot indication generation unit pass through the second polarization unit and are blocked by the first polarization unit. The first and second polarization unit comprises a linear polarizer or a circular polarizer.
