With superior technical and chemical properties, sapphire windows can be found in applications across the whole optical industry as well as in the field of measurement and analytical instrumentation. They are widely used for scanner windows, high-pressure systems, high vacuum systems, infrared surveillance systems and plasma systems.
Because Sapphire is a birefringent material, certain optical and sensor applications require the sapphire material to be c-cut. CRYSCORE can provide custom sapphire optical windows with any specifications you need.
