Embodiment 1
[0088] Refer to the following Figure 1 to Figure 2 The optical system 100 of Embodiment 1 of the present application will be described.
[0089] figure 1 A schematic structural diagram of the optical system 100 of Embodiment 1 is shown. Such as figure 1 As shown, the optical system 100 sequentially includes a first lens L1, a second lens L2, a third lens L3, a diaphragm STO, a fourth lens L4, a fifth lens L5, a sixth Lens L6, seventh lens L7, eighth lens L8 and imaging surface S19.
[0090] The first lens L1 has negative refractive power, and its object side S1 and image side S2 are both spherical surfaces, wherein the object side S1 is concave at the near optical axis, and the image side S2 is concave at the near optical axis.
[0091] The second lens L2 has a negative refractive power, and its object side S3 and image side S4 are both aspherical, wherein the object side S3 is convex at the near optical axis, and the image side S4 is concave at the near optical axis.
