Abstract

To reduce the formation of hairline cracks in systems containing alternate optically active layers of MgF2 and TiO2 (3-6) of average optical thickness greater than 100 nm at least one MgF2 and one TiO2 layer (2) of thickness less than 1 DIVIDED 5 and of the average thickness of the optically active layers (& preferably smaller than 1 DIVIDED 40) are inserted as auxiliary layers between the system and the base (1). Applications are for thermal filters, beam splitters and highly reflective metal-free mirrors. <IMAGE>
