Title:
OPTICAL SYSTEM
Document Type and Number:
Japanese Patent JP3933439
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an optical system which permits adjustment of the focal distance, adjustment of the imaging position, and the like with a simple structure in which an arbitrary portion of the optical system is selectively used by shifting a beam of light passing through the interior of the optical system by bending the optical system.
SOLUTION: In the imaging optical system composed of at least two optical elements S1 and S2, the characteristics of the optical system such as magnification are varied by decentering each other at least the two optical elements S1 and S2.
