Light emitting apparatus for providing dermatological treatment comprising a housing, a light emitting source 12 provided in the housing arranged to emit light energy along an energy pathway to external of the device. A filter arrangement 18 positioned in the energy pathway having at least a first 18a and a second light 18b energy filtering portion together combining to span across the energy pathway for filtering the light energy passing to external of the device. Multiple filter parts 18a,18b can experience greater stress due to the heat produced by the light emitting source 12.
