Abstract
An optical sensor for the ascertainment within a medium of a measured value of a measured parameter of process automation technology, comprising: a light source for transmitting transmission light; a prism; and a receiver for receiving reception light and generating a reception signal therefrom, wherein the measured value is ascertainable from the reception signal, wherein a first optical path from the light source to the medium is defined at least via the prism, wherein a second optical path from the medium to the receiver is defined at least via the prism, wherein the transmission light passes through the prism and is transformed within the medium into reception light, which passes through the prism to the receiver, and wherein the first optical path and the second optical path are essentially parallel to each other.
