Olympus Fluoview 1000
This is part of the Backprojected Pinhole Calculator.
Details
From Olympus R&D: the microscope reports the side-length of a square pinhole in microns (µm). Use this reported value (named C.A, part of the general information in the metadata-file, right below Confocal 'ON") as an input in the form below.
The shape factor is $$c=1/\sqrt{\pi}\approx0.5642$$.
The system magnification is 3.82, as reported by Olympus engineers but the value that you are asked to fill in below is the "Objective Magnification" (usually 60X or 100X)
