Device for measuring light-activated fluorescence and its use
First Claim
1. A device for measuring fluorescence excited by light comprising a measuring head, the measuring head comprising:
- a) an upper measuring head region having a face designed to have a fluorescing material applied thereto, or be in contact with a fluorescing material, or with a support having fluorescing material applied thereto;
b) at least one light source which emits light of at least one wavelength which excites at least one fluorescence, and thus, fluorescent light, in the at least one layer;
c) at least one first optical conductor which directs the light from the at least one light source directly into or in the direction of the fluorescing material;
d) at least one detector for measuring the intensity of the fluorescent light; and
e) at least one second optical conductor receiving the fluorescent light generated in the fluorescing layer, the at least one second optical conductor directing the fluorescent light onto the at least one detector;
wherein the end faces of the at least one first optical conductor and the at least one second optical conductor are arranged relative to one another as a function of their numerical apertures to achieve accurate measured values of the intensity of the fluorescent light by having the entry and/or exit cone of the said at least one optical conductor overlap the entry and/or exit cone of the at least one second optical conductor.

Abstract
The invention relates to a device for measuring light-activated fluorescence of at least one coating that contains a fluorescent material, and its use for measuring fluid materials which cause fluorescence-quenching in at least one of the fluorescent coatings. To activate the fluorescence, at least one first light wave-guide is directed onto at least one coating applied to a support and the fluorescent light is directed at a detector by means of at least one-second light wave-guide, in order to determine the intensity of the fluorescent light. The end faces of the different fluorescent light wave guides are then arranged to have overlapping entry and/or exit cones and/or be of a shape substantially identical to the at least one coating containing a fluorescent material, in such a way that an accurate measurement of the fluorescence intensity can be attained, and that the light source(s), light wave guides and the detector(s) are lodged in a measuring head.
