ACETRON offers a wide selection of evaporation materials for all PVD processes. Our product range comprises dozens of evaporation materials including special mixtures, fluorides, oxides, sulfides and metals. They are available in various forms including granules, tablets and purities in quantities ranging from several grams to hundreds of kilograms. Our extensive manufacturing capabilities allow us to custom prepare nearly and material to your exact specification.
All evaporation materials are designed and manufactured to improve the quality and performance of your evaporation processes. Reproducibility of every single batch ensures that desired product characteristics can be repeatedly achieved in our customer’s evaporation processes.
ACETRON Low Refractive Index Material
This is a type of coating-type low-refractive-index material that effectively reduces optical refractive index. This material can form high-transmittance, high-reliability low-refractive-index thin films. It enhances the light reception efficiency of optical sensors, reduces ghosting and glare caused by lens surface reflections, and addresses optical issues in various displays such as CIS, CCD, OLED, micro LED, LCD, etc.
Features
Low-refractive-index thin film material with controllable refractive index
High transparency coating material
Thermosetting material
Suitable for applications requiring optical design (such as light reflection suppression, light extraction, etc.)
