Figure 1a is a diagram showing the relationship between the incident ray and the reflected ray when a reflecting mirror is attached to the reflecting surface of the pentagonal prism of an embodiment of the laser beam squareness measuring device of this invention, and Figure 1b is a diagram showing the relationship between the incident ray and the reflected ray. Figure 1c is a plan view of the state in which the emitted light is bent at a right angle by a reflecting mirror and returns to its original position. Figure 1c is a state in which the reflecting mirror is removed from the state shown in Figure 1b and the light beam is bent at a right angle and travels straight. Figure 2 is a diagram showing how to attach the reflective mirror to the pentaprism in close contact with it, Figure 3 is a diagram showing how to adjust the pentaprism so that the incident light and reflected light match, and Figure 4 is a diagram showing how to adjust the pentaprism so that the incident light and reflected light match. is a diagram of the principle of the pentaprism, FIG. 5a is a diagram of the coordinate system in the pentaprism, FIG. 5b is a cross-sectional view of FIG. Figure 7a shows the conventional method of setting the principal plane by leveling, and Figure 7b shows the conventional method of setting the principal plane with the reflecting mirror separated from the reflecting surface of the pentaprism. It is a diagram. 1...Pentaprism, 2...Reflection mirror, 3
