Commonly referred to as a Dip Probe or Transmission Probe and used for liquids spectroscopy. These assemblies contain two fibers using a lens to collimate the light from one fiber through an open section, through which a liquid can pass. The light is then reflected off of the mirror and passes through the liquid and lens a second time, where it is refocused onto the second fiber for transmission to the analyzing instrument, typically a spectrometer. The optical pathlength in this design is double the physical opening of the replaceable tip. Other designs can be manufactured for specific applications including dissolution and harsh environments.

Shown below are two standard designs for Furcation Tubing and for Monocoil
