Measurement apparatus for non-contact measurement of thickness of optical lens center

一种非接触测量光学透镜中心厚度的测量装置

Abstract

Disclosed in the utility model is a measurement apparatus for non-contact measurement of a thickness of an optical lens center. The measurement apparatus is characterized in that the measurement apparatus comprises a light source, a measuring assembly I, a measuring assembly II, a spectrograph and a calculation control unit. The measuring assembly I includes a focusing system, a through hole assembly I, a spectroscope, a dispersion lens, and a to-be-measured part; and the measuring assembly II consists of a through hole assembly II and a transmission optical fiber. Besides, the through hole assembly II and the through hole assembly I are symmetrically arranged by taking the spectroscope as the center; the transmission optical fiber and the calculation control unit are connected with the spectrograph. According to the utility model, the measurement apparatus with advantages of simple structure, convenient usage and good stability has a great promotional value.
