CUVETTE FOR EXCITATING OPTICAL WHISPERING GALLERY MODES IN DISK OPTICAL DIELECTRIC MICROCAVITIES IN VARIOUS GAS AND LIQUID ENVIRONMENTS Russian patent published in 2017 - IPC G01N21/00 

FIELD: measuring equipment.

SUBSTANCE: cuvette for the optical microcavities with the whispering gallery modes, includes a casing with an opening in the upper end, adapted to fill the test environment and equipped with the side windows for input and output radiation. The optical communication element is fixed inside the casing with the mounting tab, opposite which is a window for visual observation is made in the front wall of the casing. The opening in the upper end is provided with a nozzle, on which an elastic sleeve is installed in a preload for sealed inserting the positioning system of the microcavities inside the cuvette and their optical aligning against the optical communication element.

EFFECT: increasing measurement accuracy and assuring access to the positioning system management for optical alignment of the microcavities inside the cuvette against the optical communication element directly during the measurement.
