FIBRE-OPTIC SWITCH OF LASER SPECTROMETER Russian patent published in 2017 - IPC G01N21/64 G02B6/36 

FIELD: physics.

SUBSTANCE: fibre-optic switch includes a fibre-optic sensor, lasers, fibre-optic connections of the lasers with the sensor, laser power control devices, a fluorescent signal analyzer, and a computer control and data processing system. The optical fibre of the sensor is connected to a guiding system, in which the end of this fibre is fixed on a flat surface of the substrate by means of a groove in the plane of the second substrate. The third substrate with three grooves fixes, with respect to the first substrate, the ends of the two fibres transmitting the fluorescence exciting fluorescent lasers and the end of the third fibre transmitting the fluorescence emission. The opposite ends of these fibres are located in the focal planes of the lenses, between the lenses of which there are replaceable optical filters. In the conjugate focal planes of the objectives, the ends of the fibres and fibres associated with the lasers are located, connected with the input of the analyzer of the fluorescence spectrum.

EFFECT: increasing the reliability and expanding the functionality of the device.
