Specifically, when the spherical normal of the spherical prism is perpendicular to the positioning surface 3 and the prism plane of the spherical prism is parallel to the angle reference plane 2, the spherical normal angle is equal to the inclination angle of the positioning surface 3. When the spherical normal angle deviates, even if the spherical normal of the spherical prism is perpendicular to the positioning surface 3, the prism plane cannot be parallel to the angle reference plane 2, and at this time, the angle deviation value of the prism plane relative to the angle reference plane 2 is the difference value between the spherical normal angle and the inclination angle of the positioning surface 3.
As a preferred embodiment of the present application, the measuring tank 1 includes a bottom plate 11, a front plate 13 is vertically arranged on the bottom plate 11, the angle reference plane 2 is a side surface of the front plate 13, a wedge block 14 with an inclined surface facing the angle reference plane 2 is further arranged, a plurality of positioning pieces 15 forming a positioning surface 3 are arranged on the inclined surface of the wedge block 14, and the positioning surface 3 and the inclined surface of the wedge block 14 are parallel to each other.

The hand is slightly forced to prop against the top of the spherical prism to be measured, so that the spherical surface of the spherical prism to be measured is tightly contacted with the positioning surface 3, and the plane of the prism is in line contact with the supporting piece 4 on the angle reference plane 2.
2) The angle deviation value of the prism plane relative to the angle reference plane 2 is measured by using the angle gauge 5, and the angle deviation value is the difference value between the spherical normal angle of the spherical prism and the inclination angle of the positioning surface 3.
3) And calculating the spherical normal angle of the spherical prism by using the known angle of the inclined angle of the positioning surface 3 and the measured angle deviation value. To facilitate calculation, the angle of the tilt angle of wedge 14 may be processed to be a standard value for the spherical normal angle of the spherical prism.
As a preferred embodiment of the present application, the front plate 13 is a transparent light-transmitting plate, and the transparent light-transmitting property of the front plate 13 facilitates the measurement of the goniometer 5.

As the preferred embodiment of the application, the inclined surfaces of the angle reference plane 2 and the wedge-shaped block 14 are respectively provided with a fixed block 16 for assisting in fixing the ball, so that the ball is accurately positioned.
As a preferred embodiment of the present application, both sides of the wedge block 14 are provided with side baffles 17 for auxiliary fixation to prevent the right and left tilt angles of the spherical prism to be measured from being excessively large.
In the actual measurement process, the device for rapidly measuring the spherical normal angle of the spherical prism only needs to put the spherical prism to be measured into the measurement groove 1, and then records the reading of the protractor 5 to finish a measurement process.
