Abstract
An illumination apparatus for outputting an output light includes a first light source configured to emit first light with a first peak wavelength in a first range of 660 nm to 699 nm and a second light source configured to emit second light with a second peak wavelength in a second range of 689 nm to 705 nm. The second peak wavelength is larger than the first peak wavelength by at least 5 nm and the second light source is configured to be switched on and off independently from the first light source. The apparatus is configured to output the first light as the output light if the second light source is switched off and to output the first light and the second light as the output light if the second light source is switched on.
