Axetris manufactures customized diffractive optical elements (DOEs) with up to 16 levels in silicon and fused silica on 150 and 200mm wafers. Both materials may be used in transmission and reflection, the latter usually requiring the application of surface metallization.
The Axetris DOE portfolio covers single chips typically sized in the millimeter range as well as undiced post-processed customer wafers.
