However, for obtaining accurate values of the optical constants of surfaces, alinement is critical.
The prisms may now be rotated in their holders until the scale readings are 0 [+ or -] 180[degrees], and 90 [+ or -] 180[degrees], and the alinement is complete.
Fortunately, with certain assumptions, even in this case alinement may be achieved quite accurately.
