Description

technical field [0001] The invention belongs to the technical field of optical detection, and relates to an arc height and radius detection device and a detection method suitable for spherical optical alignment plates, templates, lenses or spherical clamping molds. Background technique [0002] Radius of curvature and arc height are key parameters for processing optical parts and determining their performance. The error of radius of curvature will affect the focal length of the lens, which in turn will affect the imaging distance and magnification of the lens. With the continuous development of optical technology, higher requirements are put forward for the processing accuracy of optical parts, and the processing control of various parameters is more stringent. For spherical parts, how to precisely control its curvature radius has also become a problem that often needs to be solved in processing. [0003] In the prior art, the measuring ring device is generally used to meas...

Problems solved by technology

However, since the three positioning claws must always be strictly kept on a circle with a fixed center in a certain way, the overall structure is more complicated, there are many interlocking components, and the processing precision is high. In addition, the device is driven by a stepping motor. , so the cost is higher
