Abstract

The invention discloses a fast and high-precision plane parallelism measuring device comprising a measuring mechanism, a charge amplifying differential self-adjusting gain sampling circuit, and a sampling control and main processor. According to the measuring device, fast and high-precision measurement of the parallelism is realized based on a positional relationship between a center electrode anda to-be-measured target. The fast and high-precision plane parallelism measuring device is suitable for any plane that is made of a plane material or a glass panel transparent sheet material and thushas the wide application range and high usability. A metal panel plane can be measured directly and a non-metal panel can be measured in a non-contact manner by a measured target, so that the surfaceis protected from being damaged. The fast and extremely-high-precision measurement of the parallelism is realized.

Description

technical field [0001] The invention relates to a plane parallelism measuring device, in particular to a fast and high-precision plane parallelism measuring device. Background technique [0002] In the field of optical processing and mechanical processing, it is often necessary to process flat glass such as optical windows, optical filters, flat mirrors and other components. In mechanical processing, a type of high-precision structural parts will also be processed, which has an impact on the parallelism between the parts. Strict requirements, such as the optical window directly affecting the parallelism of the optical axis of the sensor, require an accurate measurement of the parallelism between the two used surfaces.
