Apparatus for optical measurement of eyeglass frame groove for spectacles lenses, has frame and optical pickup unit that are rotated at specific degree, such that optical axis of pickup unit is aligned to side view of frame

摘要

#CMT# #/CMT# The apparatus has to-be-measured spectacle frame (15) that is detachably attached to holding device. The optical axis of optical pickup unit is aligned to frontal view (16) of spectacles frame in vertical direction. The frame and optical pickup unit are rotated at 90[deg] tilt, such that optical axis of optical pickup unit is aligned to side view (17) of frame in vertical direction and stylus is viewed in transmitted light arrangement. #CMT# : #/CMT# An independent claim is included for method for optical measurement of eyeglass frame groove. #CMT#USE : #/CMT# Apparatus for optical measurement of eyeglass frame groove for spectacles lenses (claimed). #CMT#ADVANTAGE : #/CMT# The spatial geometric properties of eyeglass frame groove can be recorded accurately. The structure of apparatus is simplified and the cost is reduced, since the need for providing integrated sensors and recess is eliminated. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the eyeglass frame groove. 15 : Eyeglass frame 16 : Frontal view 17 : Side view.
