Abstract
A detector system having a single emitter body. The emitter body has a plurality of light emitting diodes (LEDs) for emitting a plurality of wavelengths. Each LED adapted to emit a different wavelength of light. A broadband filter is adapted to receive the plurality of wavelengths. A detector arrangement adapted to receive the plurality of wavelengths filtered by the broadband filter. A controller adapted to control the plurality of LEDs and detector arrangement.

A method for operating a detector system comprising:
- controlling a single emitter body comprising a plurality of light emitting diodes (LEDs) to emit a plurality of wavelengths to a broadband filter, each LED adapted to emit a different band of light;
- controlling a detector arrangement to receive the plurality of wavelengths filtered by the broadband filter;
- and
- processing a reference signal and a sample signal received from the detector arrangement to determine a property of a sample.
