Light source module and analytical instrument for analyzing a sample

摘要

A light source module (110) for use in an analytical instrument (112) for analyzing at least one sample (114) is disclosed. The light source module (110) comprises at least one light-emitting diode (LED, 118) and at least one light guiding rod (120) adapted to guide and shape light (122) emitted by the light-emitting diode (118). The light source module (110) further comprises at least one memory device (126). The memory device (126) has stored therein at least one driving parameter set (128), for driving the light-emitting diode (118) in such a way that desired emission properties of light (122) provided by the light source module (110) are generated.
