Electron microscopic measurement of the size of the optical focus in laser scanning microscopy [PDF]
, 2012 We describe a method for measuring the lateral focal spot size of a multiphoton laser scanning microscope (LSM) with unprecedented accuracy. A specimen consisting of an aluminum film deposited on a glass coverslip was brought into focus in a LSM and the ...
