Abstract

A fiber optic probe and optical coupler assembly for light scattering measurements, and a method for making the assembly and aligning a plurality of optical fibers therein. The probe includes a probe body with a window across its tip for protecting the interior, at least one light-transmitting fiber, at least one light-receiving fiber, and (if desired), in-line devices such as filters and lenses positioned in optical communication with the fibers. A fiber optic coupler maintains the relative alignment of the fibers, which can be cut to install filters and other in-line devices. The coupler allows the cut ends to be re-aligned quickly and accurately without the need for time-consuming procedures or costly precision alignment equipment. The probe is simple, rugged, requires no high-precision machining or optical alignment procedures in assembly, and is economical to manufacture.
