Example images from the inline and side-view microscopes. (a) A resolution standard imaged with an unmodified 10× objective in the inline microscope. The numbers next to the field of lines give the number of line-pairs per mm. A line in the 228 field is 2.2 µm thick. (b) The same resolution standard imaged with a centre-bored 10× objective. Additional scattering close to the centre bore produced blurring of the image and shadow images. 203 line pairs per mm can still be resolved. (c)–(d) Images from the side-view microscope. (c) Running liquid jet with a 5 µm scale bar. (d) 1951 USAF resolution test chart. Element 4 in group 8 gives 362 line pairs per mm.
