Description

technical field [0001] The invention relates to a detection device for an optical element, in particular to a surface type detection device for a convex aspherical optical element. Background technique [0002] Aspheric optical components have many advantages in application, especially in recent years, the emergence of new materials and the development of new manufacturing technology have made the aspheric processing technology develop by leaps and bounds. However, the manufacture of aspheric components must be combined with accurate aspheric surface detection technology to obtain qualified aspheric surfaces. Therefore, the detection of aspheric optical components has become the frontier field of optical measurement technology research. [0003] At present, most of the methods for detecting aspheric surfaces are contact and non-contact measurement methods, but there are usually some troubles in non-contact measurement. In non-contact measurement, since the geometric shape ...
