Abstract
In apparatus for detecting the degree of contamination of liquid of the type wherein the quantity of light transmitting through a liquid sample is detected, a combination of a transparent flat plate and a convex lens is interposed between a light source and a light receiver. The flat plate is in contact with the convex lens at the top of the convex lens so as to define an annular gap for accommodating the liquid sample.
