Optical assembly and a method for reducing force induced wavefront errors

Abstract

Optical assembly (1) comprising:—a optical component (2), which comprises two optical surfaces (5, 6) that enclose an internal space (7), which preferably comprises an optical fluid (8);—a compensation component (3), which has at least one adjustable optical property;—an acceleration sensor (9), which is designed to determine an acceleration, in particular gravity, of the optical assembly (1) or a part of the optical assembly;—a control unit (11), which is designed to receive at least one acceleration signal (10) from the acceleration sensor (9) and to control the compensation component (3) in order to adjust the optical property of the compensation component (3) as a function of the acceleration.
