The invention relates to a compensating device of gravity deformation of an optical element, which solves the problems that the conventional surface shape accuracy gravity compensation of the optical element has poor performance and is difficult to realize. The compensating device comprises a lens barrel unit component, a disk type lens frame, a micro force sensor, an adjusting screw, a lens barrel unit and an analog/digital (A/D) signal conversion device, wherein the disk type lens frame and the micro force sensor are used for fixing the lens barrel unit component; the adjusting screw is used for accurate adjustment; the lens barrel unit is used as a base of an adjusting device; the A/D signal conversion device is used for installation and adjustment control; a singlechip sends out a feedback regulation signal according to the dynamical quantity which is detected by the micro force sensor in real time, and then the radial force of a screw can be adjusted by controlling a precise installation and adjustment p
