Abstract

The invention discloses a projection lens for 3D printing. The projection lens comprises a front focusing lens group for compressing aperture and field of view and a rear focusing lens group for imaging and correcting aberration. The focal length of the front focusing lens group is greater than that of the rear focusing lens group, and the lens at the tail end of the optical path of the rear focusing lens group is an aspheric lens. The projection lens for 3D printing has the characteristics of high imaging quality, low distortion and small projection distance.

Description

Technical field [0001] The invention relates to the technical field of optical lenses, in particular to a projection lens for 3D printing. Background technique [0002] The main function of the traditional projection lens is to project the micro display chip to form a larger display screen. For traditional projection lenses, what is needed is a projection lens with a large magnification (100x), a large projection distance (1500mm), and more concerned about the center image quality. Traditional projection lenses can no longer meet the needs of 3D printing optical machines that require low magnification, short projection distance, low distortion, and high-quality full-screen projection images. A new structure of projection lens is needed to meet the needs of 3D printing. The demand for projectors. Summary of the invention [0003] The purpose of the present invention is to provide a projection lens for 3D printing, which has the characteristics of high imaging quality, low distort...
