Figure 1 is a side view of the conventional processing method;
The figure shows a reflection image of an incident image within the field of view of an autocollimator when the right angle part is an obtuse angle or an acute angle, FIG. 3 is a front view showing the processing state, and FIG. 4 is a side view showing the processing state. 0 is a conventional angle jig, 1 is a right-angle prism, 2 is a side surface of the right-angle prism, 3 is a polished surface of the right-angle prism, 3-1 is the bottom surface of the right-angle prism, 3-2 and 3-3 are the sides of the right-angle prism. The other two surfaces, 4 is an autocollimator, 5 is when the right angle of the right angle prism is obtuse, 6 is when the right angle of the right angle prism is acute, 7 is the incident image, 8 is the reflected image, 9 is the glass jig, 10 is Plane plate, 11 is Yatoi glass jig.
