Curved surface reflecting type ultra-short focal projection lens based on mems

The invention relates to the field of optics, and provides a curved surface reflecting type ultra-short focal projection lens based on mems. The curved surface reflecting type ultra-short focal projection lens based on the mems comprises a short focal projection lens body which comprises a laser light source module, a scanning module and a free-form surface reflecting mirror. The light rays emitted by the laser light source module pass through the scanning module and the free-form surface reflecting mirror in turn. The curved surface reflecting type ultra-short focal projection lens based on the mems has sufficient light intensity, high resolution and wide color gamut. Emergent light of the laser light source module is incident to the laser scanning module and then emergent out of the scanning module and then incident to the free-form surface reflecting mirror and reflected to a screen through the free-form surface reflecting mirror so as to realize projection. 本发明涉及光学领域。种基于mems的曲面反射式超短焦投影镜头，包括短焦投影镜头主体，短焦投影镜头
