    Abstract: The invention proposes an apparatus (110) for determining at least one optical property of a sample (112). The apparatus (110) comprises a tunable excitation light source (114; 410) for applying excitation light (122) to the sample (112). The apparatus (110) also comprises a detector (128, 130; 312) for detecting detection light (132, 136; 314) coming from the sample (112). The excitation light source (114; 410) comprises a light-emitting diode array (114) which is at least partially in the form of a monolithic light-emitting diode array (114). The monolithic light-emitting diode array (114) comprises at least three light-emitting diodes (426) each with a different emission spectrum.
