The invention relates to a refraction and reflection projection optical system with a large view field. Light transmits through first optical glass, a first lens, a first mirror, a second lens and a third lens along a light transmission direction. The first optical glass comprises a projection portion and a reflection portion, and all the optical elements are positioned on the same optical axis. The refraction and reflection projection optical system with the large view field is an i-ray doubled projection optical system, distortion, field curvature and astigmatism in the large view field can be corrected, and double-telecentric objective image space is realized. Besides, numerical aperture design of NA0.1 is achieved and actual product requirements are met, while large exposure view field is realized and the number of the lenses is reduced to five.
