Abstract

In order to increase measuring sensitivity of a fluorometer, a transmitter of monochromatic test light beam is arranged opposite a receiver of a measuring light beam. A measuring chamber including a fluorescent indicator space is arranged between the transmitter and the receiver. The distance between the transmitter and the receiver is adjustable to match to the thickness of the measuring chamber.
