Multifunctional portable glass surface stress gauge

The invention discloses a glass surface stress meter which comprises an illumination unit and a detection prism unit, the detection prism unit is provided with a detection surface used for being attached to the surface of detected glass for detection, and the detection surface receives at least two illumination light beams from the illumination unit. The at least two detection light paths are arranged side by side and are used for detecting the surface stress of at least two types of glass with different refractive indexes. According to the embodiment of the invention, the multifunctional portable glass surface stress meter arranges more than two measuring systems with the same principle in parallel, stable and reliable optical detection can be provided without replacing key elements and debugging corresponding optical systems, and the use of the glass surface stress meter is greatly facilitated. 本申请公开了一种玻璃表面应力仪，其包括照明单元和检测棱镜单元，检测棱镜单元具有用于与被检测玻璃表面贴合以进行检测的检测表面，其中所述检测表面接收来自照明单元的至少两个照明光束，以形成并排布置的至少两个检测光路，用于检测至少两种不
