Embodiments of the disclosure generally relate to a reflector for use in a thermal processing chamber. In one embodiment, the thermal processing chamber generally includes an upper dome, a lower dome opposing the upper dome, the upper dome and the lower dome defining an internal volume of the processing chamber, a substrate support disposed within the internal volume, and a reflector positioned above and proximate to the upper dome, wherein the reflector has a heat absorptive coating layer deposited on a side of the reflector facing the substrate support.
