ABSTRACT:
A reflector for use in a projection system comprises an anodized metal substrate having a metal oxide layer. The metal oxide layer has a plurality of pores. A light absorbing pigment is deposited into each of the pores such that the light absorbing pigment and the metal oxide layer form a light absorbing layer on the metal substrate.
