WebFlatness measurements require that optical elements IK1 and RK1 are aligned along laser beam as shown in the figure below for the first axis. Element IK1 is stationary and element RK1 is moved. Other axes can be measured with the use of one or two beam benders with constant position of the laser head, or by moving the position of the laser head ... WebOptical Quality Polishing.

WebFlatness - Metrology Measurement Optical Flats Optical flats are used to test the flatness of fine-lapped surfaces such as the measuring faces on gauge blocks, measuring inserts, measuring tables, micrometers etc., which have to meet extremely high demands on …
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.
