Abbe refractometer standard block and valuing method thereof

The invention discloses an Abbe refractometer standard block and a valuing method thereof, and belongs to the technical field of testing. The Abbe refractometer standard block is made of an optical glass material with a refractive index of 1.3-1.7; thestandard block is cylindrical, and comprises at least three plane cylindrical surfaces perpendicular to the same plane, the included angle theta between a first plane cylindrical surface (1) and a second plane cylindrical surface (2) ranges from 89 degrees 59 minutes to 90 degrees 1 minute, the included angle beta between a third plane cylindrical surface and a second plane cylindrical surface (3) ranges from 22.5 degrees to 67.5 degrees, and the three plane cylindrical surfaces are polishing surfaces. According to the invention, a minimum deviation angle method, an auto-collimation method and a V-prism refractometer can be respectively used for valuing the standard block, so that the current situation that the standard block of the abberefractometer with a cubo
