Abstract

We have designed and constructed a white light optical sensor for optical particle counter (OPC). The optical system of the sensor is a right-angle scattering type optics. It consists of an illumination system and a collection system for scattered light. A large illuminating aperture angle of 24 degrees is obtained by applying an aplanatic singlet in the illumination system, and a large collecting aperture angle of +/- 44 degrees is achieved by a spherical mirror. With the two large apertures, high signal-to-noise ratio and good monotonic light scattering response have been gained.
