Abstract:
An optical system and a head-mounted display device, which belong to a design scheme for a direct-transmission-type optical structure having a short focus, high luminous efficiency and high resolution. The optical system has better imaging quality. The optical system comprises a third lens (3), a second lens (2) and a first lens (1), which are sequentially arranged in the propagation direction of incident light, the effective focal length f1 of the first lens (1) and the effective focal length f2 of the second lens (2) both being greater than the effective focal length f of the optical system.
