ABSTRACT:
An optical interface coupler for coupling a flow cell to an optical absorption analyzer. The flow cell and analyzer are operable to transmit light through a fluid flowing through a chamber within the cell and analyze the transmitted light for determining certain optical properties of the fluid. The cell includes a first port through which light from a first fiber optic cable is transmitted to the chamber and a second port through which transmitted light is received and transmitted to a second fiber optic cable connected to the optical absorption analyzer. The optical interface coupler comprises a housing and a lens. The housing is releasably attachable to the cell at one of the first and second ports and defines an optical pathway therein. A cable port is in the housing for receiving one of the first and second fiber optic cables, and is in optical communication with the optical pathway. The lens is in the optical pathway spaced from the cable port and has a focal point for a given wavelength of light passing through the lens. The coupler further includes a mechanism for selectively spacing the lens relative to the cable port to control the location of the focal point of the lens relative to the cable port.
