Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing detection platform cannot adjust the measuring head and the workpiece surface to a vertical position when measuring aspheric optical elements, and cannot realize accurate measurement of aspheric optical elements. The linkage adjusts the relative position between the probe and the surface of the workpiece to ensure that the probe is perpendicular to the surface of the workpiece.

Description

technical field [0001] The invention relates to a surface shape detection device of an optical aspheric element, in particular to a five-axis optical aspheric surface detection device driven by a linear motor for different curvatures. Background technique [0002] Aspherical optical elements have many advantages in application, such as correcting the aberration of high-resolution lenses, thereby improving the imaging quality of the optical system, and one or several aspheric elements can replace multiple spherical elements, thereby simplifying the structure of the instrument and reducing the cost and effectively reduce the mass of the instrument. (Refer to literature: Zhang Yunqing. Growing demands and process challenges. Opto-Mechanical Information, 2005, 11: 14-21). Especially in recent years, the emergence of new materials and the development of new manufacturing technologies have led to rapid development of aspheric processing technology. Now, some new processes such as...
