The use of one or more wavefront modulators in the observation beam path and/or illumination beam path of a microscope provide various advantageous results. Such modulators may be adapted to change the phase and/or the amplitude of light in such a way to carry out displacement and shaping of the focus in the object space and correction of possible aberrations. The possible areas of use include confocal microscopy, laser-assisted microscopy, conventional light microscopy and analytic microscopy.

Applications of adaptive optics in microscopy

A high-aperture objective comprising a first lens L with positive refractive power f and a second lens L with negative refractive power f wherein the focal length ratio between the two lenses is in the range of &minus;0.4<(f /f )<&minus;0.1 and the total refractive power /f /f is greater than zero, two positive lenses L L whose ratio diameter d d to focal length f f satisfies the condition greater than 0.3 and less than 0.6:0.3<d /f <0.6, 0.3<d /f <0.6, a negative lens L and a collective lens L wherein the negative lens faces the front group and the focal length ratio of L and L f /f is between &minus;0.5 and &minus;2:&minus;0.5<f /f <&minus;2.
