Gavish manufactures sapphire windows for various applications in many different markets:
Sapphire Windows - scratch and explosion proof windows for flame detectors and other high performance applications
Vacuum chamber windows - hundreds of configurations used in Semiconductor process chambers where resistance to corrosive plasma is critical, while also providing high strength and broad spectral transmission. · Laser windows, cutoff filters and reflectors
Intense illumination - replacing glass and quartz windows and envelopes where high heat would melt other materials
Light guides and optical probes - for high temperature, hostile environments, and broad wavelength applications
The broad spectral response from UV through SWIR in the 200 – 3500 nm range along with the high strength, durability, and high laser damage threshold make sapphire ideal for many high performance optical window and lens applications.
Lenses and prisms - configurations such as plano/plano, plano/convex or concave, concave/convex, rod lenses and prisms fabricated per customer designs
