ABSTRACT:
Method for adjusting index of refraction of optical coating by heat treating. PLZT ceramic can be sputtered to form a thin film optical coating material for various optical applications. The fact that its refractive index can be adjusted by diffusion makes it particularly useful for antireflection coating or reflection coating on optical surfaces.
