Publication number: 20220196997Abstract: An optical system to divide a light flux from an object plane includes a first curved-surface mirror, and second, third, and fourth reflecting portions. The second reflecting portion divides and reflects light flux from the first curved-surface mirror to respective different positions on the first curved-surface mirror as first light fluxes. The third reflecting portion reflects, as third light fluxes, the first light fluxes. The fourth reflecting portion reflects the third light fluxes from the third reflecting portion. A number of reflective surfaces of each of the third and fourth reflecting portions on which the first and third light fluxes are incident is the same as a division number in the dividing of the light flux into the second light fluxes. The first and third light fluxes are reflected by the respective third and fourth reflecting portions to be image-formed so that divided images of the object plane are formed.Type: ApplicationFiled: December 9, 2021Publication date: June 23, 2022Inventor: Takashi Sukegawa
