What is the light source used to illuminate the fundus for oximetry measurements?

The light sources of the fundus camera are used to illuminate the fundus of the eye. A halogen lamp is used for observation and a xenon flash for photography. An additional filter is provided by Oxymap with the Oxymap T1 to decrease unnecessary exposure to light. This filter passes wavelengths from 545 nm to 615 nm and thus filters ultraviolet and infrared radiations.
