  • Patent number: 10606049
    Abstract: The present invention relates to an ultra-short distance projection lens with a refractive meridional image surface and a refractive sagittal image surface being isolated, including a display chip, a refractive lens group, and a rotationally symmetric reflector. The display chip undergoes imaging by the refractive lens group to form, between the refractive lens group and the rotationally symmetric reflector, a meridional intermediate image and a sagittal intermediate image that are isolated, wherein the two images undergo imaging by the rotationally symmetric reflector and astigmatism is eliminated on a screen, to form a clear picture. The present invention has a simple structure, a projection ratio 0.27 to 0.31, a magnification ratio 170 times to 220 times, and ultra-small distortion, has an optical structure that cancels out astigmatism, high resolution, very desirable tolerance, and relatively low mounting precision requirements on optical parts, and has a very high yield in mass production.
