  • Patent number: 6855941
    Abstract: A multiphoton excitation scanning laser microscope employs a laser beam source for oscillating a pulse laser beam having a wavelength range. A multiphoton excitation phenomenon takes place in a sample irradiated with the laser beam so as to emit a fluorescent light. An optical system for forming an optical path of the laser beam includes a pre-chirp compensator, a scanning optical unit and a plurality of objective lenses differing from each other in magnification and capable of being selectively arranged on the optical path. The optical system also includes a correcting mechanism for causing the pulse width of the laser beam to be constant on a cross section of the sample in the case of selecting any of the objective lenses. The correcting mechanism includes a plurality of correcting plates capable of being selectively arranged on the optical path.

  • Patent number: 6856354
    Abstract: This invention includes an RGB color camera for photographing an object under photographing illumination light, a simplified spectrophotometer for measuring a photographing illumination light spectrum, and a color correction device for calculating tristimulus value data of the object and converting the data into an input signal to a CRT monitor by using monitor profile data. On the observation side, a CRT monitor and illumination light colorimeter for measuring the tristimulus values of observation illumination light are arranged. A color correction device can perform color reproduction without being influenced by changes in the color perception characteristics of a person such as chromatic adaptation by reproducing a virtual illumination light spectrum having tristimulus values equal to those of the observation illumination light without measuring any observation illumination light spectrum.

  • Patent number: 6853481
    Abstract: A base, a frame, and an arm which constitute a microscope body are formed independently of one another, and receptacles receiving fastening members at the bottom of the frame are formed as protrusions so that the area of contact between the base and the frame is smaller than a predetermined area. The protrusions are formed so that they surround the fastening members. The protrusions increase resistance to heat conduction from the base to the frame to reduce the amount of heat which is generated from the lamp and conducted from the base to the frame. Such an arrangement reduces an image blur due to thermal deformation, thereby providing a good specimen image.

  • Patent number: 6844963
    Abstract: The present invention provides various embodiments of a double-resonance-absorption microscope which realizes a super-resolution by using double resonance absorption. In particular, a double-resonance-absorption microscope includes a light source for a pump light of a wavelength ?1 which excites a sample molecule to a first electronic excited state from a ground state, a light source for an erase light of a wavelength ?2 which excites the sample molecule to a second electronic excited state or a higher excited state from the first electronic excited state, and an overlap component for partially overlapping irradiating areas of the pump light and the erase light with each other. An emission area upon deexcitation of the sample molecule to the ground state from the first electronic excited state is partially inhibited by irradiating the pump light and the erase light through the overlap means.

  • Patent number: 6839511
    Abstract: In a camera system according to the invention, a camera body and an interchangeable lens have respective identification data tables that are congruous with each other. As an appropriate data address is indicated to the interchangeable lens by the camera body, an identification data that is stored in the identification data storage section and corresponds to the indicated address is transmitted from the interchangeable lens to the camera body. The identification data judging section of the camera body compares the identification data transmitted back from the interchangeable lens and the identification data that is stored in the identification data storage section and corresponds to the address. As a result, it is determined if the dedicated accessory device is mounted on the camera body or not.
