Abstract:
1. A multilayer observation optical microscope, comprising: a) a light source; b) an objective lens for focusing an irradiation light beam from the light source into a sample; c) a pair of convergence/collimation lenses placed on an optical axis along which the irradiation light beam from the light source enters into the objective lens; d) phase varying means arranged between the convergence/collimation lenses for varying a phase of a transmitting light beam in a given area on a plane traversing the optical axis so as to stepwise adjust a depth of an observation plane of the objective lens; and e) a confocal scanner arranged between the light source and the pair of convergence/collimation lenses, the confocal scanner including a microlens array disc disposed on a side of the light source, a Nipkow disc having plural pinholes and disposed on a side of the convergence/collimation lenses in such a manner that it is arranged coaxially and oppositely with the microlens array disc, and a dichroic mirror arranged between the microlens array disc and the Nipkow disc for transmitting the irradiation light beam from the light source while reflecting fluorescence returned from the sample.
