Abstract: In a method of observing a specimen through a fluorescence microscope, molecules that could cause double-resonance absorption process in an appropriate manner are used to dye the specimen, and the specimen is irradiated with a plurality of light beams of different wavelengths in a good timing, so that a microscopic image with high spatial resolution is obtained. In the microscope to be used in the method of observation, the specimen is irradiated with two light beams of different wavelength bands via an aperture with an annular-zonal structure and an optical system that has different in-focus positions for these two wavelength bands, so that one of the two light beam is focused on a surface of the specimen and the other light beam is defocused thereon. Consequently, the microscope achieves improvement of the spatial resolution as to overcome the diffraction limit determined by the wavelengths in use.

Abstract: A vacuum optical system has a vacuum chamber for housing an optical system used in a vacuum. The vacuum chamber is equipped with a member, on which the optical system is at least mounted, supported by such parts that when a pressure in the vacuum chamber changes to deform the vacuum chamber, the amount of displacement transmitted to the optical system is smaller than a predetermined tolerance depending on an accuracy necessary for the optical system. Thus, the vacuum optical system can be obtained which does away with the need for readjustment of optical alignment and is compact.

Abstract: A method for observing a sample containing photochromic molecules having a quantum state of at least a first stable state S0 and a second stable state S3. Used are first light for exciting the photochromic molecules from the first stable state S0 to a first excited state S1 enabling optical response, and second light for exciting the photochromic molecules from the first excited state S1 to a second excited state S2 of another energy level. The sample is irradiated with the first light and the second light partly overlapping each other so that the photochromic molecules in the region irradiated with the overlapping first and second lights are transformed through the second excited state S2 to the second stable state S3, and the photochromic molecules in the region irradiated with the first light only are transformed to the first excited state S1, thereby observing the sample.
