Super-large-multiple low-distortion short-wave infrared optical system

The invention relates to an ultra-large-multiple low-distortion short-wave infrared optical system which comprises a front fixed group A, a zoom group B, a compensation group C and a rear fixed group D. The front fixed group A is composed of a negative meniscus lens A1, a biconvex positive lens A2, a positive meniscus lens A3, a negative meniscus lens A4 and a positive meniscus lens A5. The zoom group B is composed of a first gluing group and a biconcave negative lens B4, wherein the first gluing group is formed by tightly connecting a meniscus negative lens B1, a biconcave negative lens B2 and a meniscus positive lens B3; the compensation group C is composed of a biconvex positive lens C1, a meniscus negative lens C2 and a second gluing group formed by tightly connecting a biconvex positive lens C3 and a meniscus negative lens C4; and the rear fixed group D consists of a biconcave negative lens D1, a meniscus positive lens D2, a third gluing group formed by tightly connecting a biconvex positive lens D3 and
