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. Think of a table with two WebFlatness Reference Chart.

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. WebAn optical flat and monochromatic light can then be used to measure the light band flatness of the plug. Lapmaster offers two sizes of brass test plug, 3” diameter by 2-1/2” high and 6” diameter by 3-1/2” high. Both plugs have a 1/2” through hole machined on center. Brass material is used because it is soft, has sufficient weight to ... opencl array sum example https://jmhcorporation.com

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 ...
