The focussing properties of different lenses are analyzed and the results are demonstrated. A design for a special focussing optic will be presented. Its focussing properties are compared to a commonly used microscope objective in theory and experimentally.enultra-short laser pulseimaging systemfocussingfourier opticgeometrical opticnumerical approximation and analysis620conference paper
