WebFeb 1, 2016 · The Z resolution of the resulting model is dependent on the depth of focus of the individual objective. Hence, it would make little sense to use the 1× objective (which has the broadest depth of focus) in conjunction with a one micron Z-direction stepping distance.
WebBecause the height difference from peak to peak in the waveform graph is 0.204 μm, a resolution of 0.1 nm is possible by dividing the waveform graph into 2000 segments between the peaks. Optical interferometers measure changes in height by measuring the changes between light and dark in regular interference stripes. imvu card codes freeWebThe profilometer acquires the reflectance spectrum of the sample in the visible range, and is compared with a simulated spectra calculated by the software, with layer thickness … lithonia houses for rentWebJan 1, 2013 · Abstract and Figures.
