Abstract
An optical system for adjusting a proportion of light of a particular spectral band that is emitted from the optical system. A dichroic mirror is configured to reflect light of a first spectral band from a light source towards a distal end of an optical fiber while allowing light of a second spectral band to pass through the dichroic mirror. The second mirror is positioned behind the dichroic mirror and is configured to reflect light of the second spectral band. A mirror actuator is coupled to the second mirror and is configured to adjust a proportion of the light of the second spectral band that is emitted by the optical system by adjusting a position of the second mirror relative to the dichroic mirror.
