Abstract
A high-resolution imaging lens proofed against high-temperature instability includes a first lens with a negative power, a second lens with a negative power, a third lens with a positive power, a fourth lens with a negative power, a fifth lens with a positive power, and a sixth lens with a positive power. The first to the sixth lenses satisfy conditions of F1<0; 0.8>|F2/F6|>0.6, F2<0, F6>0; −3>F4/F5>−2, and 2.0<F/#. Each of the first lens, the third lens, the fourth lens, and the fifth lens is made of glass, each of the second lens and the sixth lens is made of plastic.
