Abstract

A scattered light detector comprises a first photodiode array comprising one or more photodiodes arranged in a planar, semicircular pattern on a substrate, each of the one or more photodiodes having an outer edge and an inner edge; and a notch perpendicular to the substrate and located adjacent the inner edge of each of the one or more diodes, and equidistant from the outer edges of each of the one or more photodiodes, the notch configured to accept an optical fiber oriented perpendicular to the plane of the one or more photodiodes. When there are two or more photodiodes, the photodiodes may be divided into two or more segments extending outwardly from the notch. Each of the photodiodes shares a common electrical ground. The planes of the one or more photodiodes of the first and second photodiode arrays are oriented parallel to each other and spaced a predetermined distance apart.
