Abstract
Examples of the disclosure relate to optical apparatus for providing a uniform output for different wavelengths of light. The apparatus can comprise a light guide. The light guide can comprise a first layer and a second layer and an interface between the layers. The first layer comprises an in-coupler configured and an out-coupler. The interface between the first layer and the second layer comprises a beamsplitter arranged to split beams of light. The interface is arranged to retain in-coupled light of a first wavelength range in the first layer and split beams of light of a second wavelength range so that part of the in-coupled light of the second wavelength range is reflected into the layer from which the light has travelled and part of the in-coupled light of the second wavelength range passes into the other layer.
