Optical table flatness
WebFlatness – The condition of a surface having all elements in one plane. Parallelism – The condition of a surface, line, or axis which is equidistant at all from a datum plane or axis. It's not rocket science. ... Flatness is a feature compared to itself, while parallelism requires that a feature be compared to a datum.

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 ...
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.
