This is because the lower portion of the interferogram is going out of focus; out of focus means less interference. Inside an optical interference profiler, a light beam is split, reflecting half the beam from a test material which is passed through the focal plane of a microscope objective, and the other half of the split beam is reflected from the reference mirror. Looking at the interferogram at right, you might notice that the light and dark bands near the bottom are not as bright or dark as the ones near the ruler marks.

These can be: Extra-small, with diameters as small as 0. The inspection capabilities of the profilometer are determined jointly by its two main components: the Microcam interferometer signal processing detector and the fiber-based optical probe selected for the application.

    Optical Profilers Obtain Amazing Accuracy with Interferometry Hypothetically, if the wavelength is nanometers, one could estimate the distance of slope over a full wavelength by looking at the light and dark interference bands — known as interference fringes — in an interferogram.
