Title:
PRISM AND GLASS SURFACE STRESS DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/050113
Kind Code:
A1
Abstract:
Disclosed are a prism (20) and a glass surface stress detection device (100) using the prism as a detection prism. The prism (20) comprises an import prism part (21) and an export prism part (22), which are integrally formed. The import prism part (21) and the export prism part (22) are respectively provided with a first working surface (21a) and a second working surface (22a), which are coplanar. The prism (20) is provided with at least one groove (23) that is located between the import prism part (21) and the export prism part (22) and that is perpendicular to the first working surface (21a) and the second working surface (22a), and the at least one groove (23) forms a diaphragm used for stopping light from being propagated from one side of the first working surface (21a) to one side of the second working surface (22a). The import prism part (21) and the export prism part (22) are integrally formed, and the diaphragm is formed on the integrated prism by forming the groove (23), accordingly, coplanar working surfaces are ensured on one hand, and on the other hand, the prism has a simple and compact structure and is convenient to manufacture.
