Abstract

1347039 Anti-reflection coating CANON K K 29 Oct 1971 [29 Oct 1970] 50403/71 Heading G2J A three-layer coating of thicknesses #/ 2 , #/ 2 and #/ 4 (from the optical element) and also of refractive indexes n 2 >n g >n 1 >n 3 where n g is the refractive index of the optical element and n 1 - n 3 are the layers crushing from the element. The invention applies specially to n g >1À70 and specified coating materials are Al 2 O 3 , CeF 3 , CeO 2 ZnS, ZrO 2 M g F 2 .
