Thin Film Materials for Optical Interference Filters

Article Preview

Abstract:

Abstract. Microstructural, optical and mechanical properties of oxide and fluoride films are examined. Superior optical quality, durability and environmental stability are achieved for oxides deposited by ion assist reactive ion beam sputtering and thermal evaporation. The materials and deposition techniques are discussed with regards to manufacturing of optical interference filters for near-UV – mid-IR wavelengths. High performance of thin film materials and optical filters is demonstrated.
