Figure 7.15 Straight-line layout. The path lengths can be determined from the distances and
indices of refraction. Light on one path passes through the substrate of the beamsplitter once, but
light on the other path does so three times. Increased index of refraction lengthens the optical
path, but shortens the geometric path.
