Abstract
Abstract A reflection fluorometer has a cylindrical measuring optical waveguide with a capillary-like structure which permits a beam of pulsed light in the form of a conical envelope to be directed onto a front face of the measuring optical waveguide. The reflection fluorometer comprises a device for timed measurement of the emission light which emerges essentially radially from the measuring optical waveguide.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
51 words
A reflection fluorometer, comprising: a capillary-shaped measuring fiber-optical waveguide; means for providing a conical envelope shaped beam of pulsed light onto a front face of the measuring optical waveguide; and a device for the time-resolved measurement of emission light which emerges in a substantially radial manner from the measuring optical waveguide.
Claim 2
Dependent Claim
51 words
A reflection fluorometer, comprising: a capillary-shaped measuring fiber-optical waveguide; means for providing a conical envelope shaped beam of pulsed light onto a front face of the measuring optical waveguide; and a device for the time-resolved measurement of emission light which emerges in a substantially radial manner from the measuring optical waveguide.
Claim 3
Dependent Claim
29 words
A reflection fluorometer according to claim 1, further comprising a device for wavelength-resolved measurement of emission light which emerges in a substantially radially manner from the measuring fiber-optical waveguide.
Claim 4
Dependent Claim
22 words
A device according to claim 1, wherein the measuring optical waveguide has a mirror on the end opposite the beam of light.
Claim 5
Dependent Claim
32 words
A reflection fluorometer according to claim 1, further comprising an auxiliary sensor for measuring a portion of reflected light or of emission light for the compensation and correction of the measured values.
Claim 6
Dependent Claim
28 words
A reflection fluorometer according to claim 1, wherein the measuring fiber-optical waveguide is situated on a focal line of a reflector which has an elliptic or paraboloidal cross-section.

Claim 9
Dependent Claim
33 words
A reflection fluorometer according to claim 2, further comprising an auxiliary sensor for measuring a portion of reflected light or of the emission light for the compensation and correction of the measured values.
Claim 10
Dependent Claim
28 words
A reflection fluorometer according to claim 2, wherein the measuring fiber-optical waveguide is situated on a focal line of a reflector which has an elliptic or paraboloidal cross-section.
