Embodiment 1
[0083] Please refer to Figure 1 to Figure 2C As shown, the optical system 100 includes a first lens 110 , a stop STO, a second lens 120 , a protective glass 130 and an imaging surface S7 arranged in sequence along the optical axis from the object side to the image side.
[0084] The first lens 110 has positive refractive power, the object side S1 of the first lens 110 is convex at the near optical axis, and the image side S2 of the first lens 110 is concave at the near optical axis. The second lens 120 has positive refractive power. The object side S3 of the second lens 120 is convex at the near optical axis, and the image side S4 of the second lens 120 is also convex at the near optical axis.
[0085] In the first embodiment, the reference wavelength of the focal length of each lens is 10000.000 nm, and the reference wavelength of the Abbe number and the refractive index are both 587.56 nm. The relevant parameters of the optical system 100 are shown in Table 1, wherein, in ...
