LIGHT SOURCE FOR FTIR BIOSENSOR

摘要

The invention provides a light source for a biosensor. The light source comprises a LED and a corrector means. The corrector means is for correcting the light emitted from the LED by filtering out most of the unwanted angles emitted by the LED. The corrector means comprises one or more holes having a large aspect ratio, i.e., having a depth that is larger than the diameter. The inside of the hole is non-reflecting and light-absorbing in order to avoid unwanted reflections of light inside the hole. The invention further provides a biosensor device comprising the light source according to the invention.
