Fiber optic device, optical system and method for optical measurement

Abstract

The invention relates to a fiber optic device (10) for an optical system (100), including: (a) a first fluid container (12) including a fluid inlet (12a), a fluid outlet (12b), and a light transparent window (12c); (b) a second fluid container (14) including a fluid inlet (14a), a fluid outlet (14b), and a light transparent window (14c); and (c) a hollow core optical fiber (16) fluidically connecting fluid outlet (12b) of first fluid container (12) to fluid inlet (14a) of second fluid container (14) and arranged to direct light incident on light transparent window (12c) of first fluid container (12) to light transparent window (14c) of second fluid container (14), wherein hollow core optical fiber (16) is a, preferably twisted, single ring hollow core optical fiber. The invention also relates to optical system (100) including fiber optic device (10) and to a method for optical measurement using optical system (100).
