Abstract: A reflective inner red dot sight optical system with improved monochromaticity and concealment, a two-light three-color optical system, and a sight thereof. The reflective inner red dot sight optical system comprises an LED chip (1) and a lens (3) for reflecting light emitted from the LED chip (1). A filter (2) provided with a narrow-band interference filter coating is provided near the LED chip (1) and located between the LED chip (1) and the lens (3). The filter (2) is used to filter out wide band waves not in the central wavelength of the light reflected from the lens (3) into the eye, thereby improving the monochromaticity of the light entering the eye. Viewed from a distant position in a direction corresponding to a cemented lens, the filter filters out part of the light energy emitted from the LED chip (1), thereby avoiding the case in which an excessive amount of light is emitted and therefore spotted, and improving the concealment of the sight. The invention provides a red light source and a green light source emitting light on mutually perpendicular planes, and uses a prism and a total reflection coating or a transmission coating to generate green, red or yellow light by means of a control circuit, thereby greatly reducing the number of light sources and the size and the weight of the sight.
