A simple but precise method for quantitative measurement of the quality of the laser focus in a scanning optical microscope
We report a method for characterizing the focussing laser beam exiting the objective in a laser scanning microscope. This method provides the size of the optical focus, the divergence of the beam, the ellipticity and the astigmatism. We use a microscopic‐scale knife edge in the form of a simple tran...
