Abstract: An optical system and an optical camera working at a far-infrared waveband are provided, the optical system along the optical axis from the objection side to the image side includes: a metalens and a spherical lens; the metalens is configured to correct higher-order residual wavefront aberrations; the spherical lens is configured to correct lower-order primary wavefront aberrations; the metalens and the spherical lens are configured to correct aberrations; an absolute value of the curvature radius of an objection-side surface towards the objection side for the spherical lens is greater than an absolute value of the curvature radius of an image-side surface towards the image side for the spherical lens; the optical system satisfies the following condition: 0.83≤f/D≤0.92; where f is an effective focal length of the optical system, and D is the entrance pupil diameter of the optical system.
