WebWhen the flat surface of the test optic is placed against the optical flat, fringes appear whose shape dictates the surface flatness of the optic under inspection. If the fringes are evenly spaced, straight, and parallel, then the optical surface under test is at least as flat as the reference optical flat. WebSet the mounted sample face down on the polishing disk of the highest grit. Apply only enough force to keep the sample from moving. Be careful not to apply to much force but make sure enough force so that you have a secure grip on the sample. This will prevent the sample from flying out of the machine. rock song come on come on
