Fiber optic fluid flow cell for measuring optical characteristic of fluid, has vibration damper absorbing vibration arising between free end of optical fiber and flow cell body, and located in region between free end side and cell body

摘要

#CMT# #/CMT# The flow cell (10) has an optical fiber (40A) for coupling and/or uncoupling an optical signal (50) into fluid (30A). The optical fiber with a free end (45A) extends into a flow cell body (20), and a vibration damper absorbs vibration arising between the free end of the optical fiber and the flow cell body. The vibration damper is located in a region between a side of the free end, which is opposite to the flow cell body, and the flow cell body. The damper is formed by deforming the flow cell body in a region of the free end. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a flow cell. #CMT#USE : #/CMT# Fiber optic fluid flow cell for use in a fluid separating device (claimed) for measuring an optical characteristic of fluid flowing through the flow cell. #CMT#ADVANTAGE : #/CMT# The vibration damper absorbs the vibration arising between the free end of the optical fiber and the flow cell body, thus reducing signal fluctuations and noise in the flow cell, which results from movements of the optical fiber in the flow cell due to pressure instabilities. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a principal representation of a fiber optic fluid flow cell. 10 : Flow cell 20 : Flow cell body 30A : Fluid 40A : Optical fiber 45A : Free end 50 : Optical signal.
