ABSTRACT:
A turbidity sensor is provided with two plates which each have an aperture formed therethrough. The apertures are aligned to define a light passage from a light source such as a light emitting diode. By properly selecting the gap between the two plates and the size of the two apertures, the angle of divergence light emanating from the light source can be controlled and reduced to a magnitude that prevents light from passing directly from the light source to a scattered light detector of the turbidity sensor. The arrangement avoids the necessity of using expensive focusing lenses.
