FIBER-GLASS CONFOCAL SCANNING MICROSCOPE Russian patent published in 2020 - IPC G02B21/00 G01N21/64 

FIELD: physics.

SUBSTANCE: invention relates to devices for recording radiation excited in local areas of the medium when focusing laser radiation. Fiber-optic confocal scanning microscope has a laser radiation source, a Y-circulator, a lens, a confocal diaphragm, a photodetector and spatial scanning devices of the analyzed region of the object. First unidirectional input of the optical waveguide of the Y-circulator is connected to the object illumination source. Optical beam of the output end of the first waveguide is directed to the end of the second waveguide at a certain angle in the axis of the second waveguide within the limits of the aperture angle of the optical fiber. Output end of the optical bidirectional second waveguide is an aperture which forms a light beam of illumination of the object through the lens and simultaneously is a confocal diaphragm filtering the radiation of the object medium response. Radiation of the medium response passes back through the lens and the second waveguide to the end of the third unidirectional waveguide. Third waveguide is located along the axis of the second waveguide. Output of the third waveguide is the output of the Y-circulator, connected to the input of the fiber-optic spectrometer. Radiating end of the second waveguide is connected to the mechanical system of displacement of this butt-end for scanning of the radiator scaled by the lens of the image of the aperture in the conjugated plane combined with the object.

EFFECT: technical result consists in expansion of functional capabilities of device and simplification of microscope design.
