WebThe best and fastest method for checking plate flatness is the use of a Flatness Gauge. This consists of a dial indicator (calibrated to 0.001mm) supported on three points and set to zero on a known flat test piece. The gauge can be used to take readings over several areas of the Lapping Plate. WebNov 6, 2024 · Flatness (Surface Flatness): The flatness of an optical platform usually refers to the amount of variation of the actual surface to be measured relative to its ideal plane in a unit area. Generally, the flatness index of foreign optical platforms is ±0.1mm/600mm×600mm.

WebIn application, one way to physically measure flatness is to use a height gage, as we can see in Figure 2. To use the height gage correctly, the part to be measured is first placed upon 3 columns with adjustable heights. Then, the height gage is run across the surface while looking at the amplitude of the needle. 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 … highway to heaven a song for jason part 2
