คุณลักษณะ

• Because of its simple configuration and short interference optical path length, it is a stable interferometer that is less affected by vibrations and temperature changes than the other two interferometers.
• Used for observing surface accuracy of reflectors, etc.
• However, the contrast of interference fringes is worse than that of other interferometers because the reflected light of the measuring surface and that of the reference surface do not have the same amount of reflected light.
