I'm not so sure about that coverage. The specs say "square, cut wafer plate, cemented onto a 75x25 mm microscope slide (photo 1)". In the samples that I bought several years ago, the actual wafer is about 19mm x 21 mm on two slides, and about 13 mm x 21 mm in the third.chris_ma wrote: I like that with 75x25mm it covers full frame at 1x.
