Comparison of conventional and scatter-plate microscope imaging: A 1951 USAF test target was used as an object. We imaged the highest resolution area of the test target, i.e. the 7th group, with smallest line thickness of 2.19 µm; (a) and (b) are the images obtained with a conventional microscope for NAs 0.16 under monochromatic and white light illuminations, respectively, whereas, (c) is their scatter-plate microscope counterpart for the same NA. The image quality, contrast and resolution of both techniques are almost equally good but the working distances of the scattering objective is comfortably long (\(\hat{z}\) = 51 mm). The scale bar is 21.5 µm.
