MULTIPHOTON SENSOR DEVICE Russian patent published in 2022 - IPC G01N21/31 

FIELD: measuring technology.

SUBSTANCE: invention relates to the field of measuring technology and relates to a multiphoton sensor device. The device includes a radiation source, a sealed cuvette, a radiation detection unit and focusing optical elements installed between the radiation source and the cuvette and between the cuvette and the radiation detection unit. The cuvette consists of a fixed part and a cover with slots, made with the possibility of sliding along the fixed part. A spike is made on the outer surface of the fixed part, and a groove is made on the inner surface of the fixed part, the end part of the fixed part facing the radiation detection unit contains a retaining wall. A microstructural optical fiber is placed in the groove of the fixed part. The groove is made in the form of a semicircle with a radius of at least 1.1 times greater than the dimensions of the microstructured optical fiber.

EFFECT: providing the ability to perform analyzes of bioanalytes in real time and a wide spectral range.
