Document Type and Number:
WIPO Patent Application WO/2023/004794
Kind Code:
A1
Abstract:
A periscope-type optical system with a shortened total length of optics is disclosed. The optical system includes a reflective optical element (P) for bending an optical path by 90 degrees from an object side toward an image side and a rear group of lenses (G_rear) on the optical path following the reflective optical element (P), wherein the rear group of lenses (G_rear) has a positive refractive power as a whole. The reflective optical element (P) has a convex curvature on a first surface (S1) of the object side and a concave curvature on a third surface (S3) of the image side.
