How to estimate the back projected pinhole value from the Airy Disk size?
Some confocal microscopes report the pinhole size with the Airy disk as unit.
Compute the backprojected pinhole radius from the following formula: <br>
backprojected_RADIUS = number_of_Airy_disks * 0.61 * lambda / NA
NA = the numerical aperture, number_of_Airy_disks = the number of disks diameters fitting in the pinhole diameter. <br>
The Airy disk diameter is the diameter of the first dark ring of the diffraction pattern in the focus of a lens, the so-called Airy disk.
