Sapphire window


He Rui optics' Sapphire windows are specialized optical components made from single crystal sapphire. They are ideal for harsh applications such as laser systems due to their high surface hardness, excellent thermal conductivity, high dielectric constant, and strong resistance to common acids and bases. Sapphire is second only to diamond in hardness, allowing sapphire windows to be thinner than other common window materials, thus offering higher transmission rates. Chemically, sapphire is single crystal alumina (Al2O3), and it has a transmission range from ultraviolet to mid-infrared, which is 330-5500nm, without coating.

He Rui Optics' Sapphire windows are suitable for use in extreme conditions, including high temperatures, high pressures, strong vacuum environments, or corrosive settings. They feature high compressive strength and resistance to acid corrosion, with a transparent range of 170 nm to 5.5 µm. Sapphire optical windows come in various diameters and thicknesses, and custom products can be produced based on specific requirements.The unique properties of sapphire, including its wide transmission range, high hardness, mechanical strength, and chemical resistance, make it an ideal choice for a variety of applications ranging from drones and autonomous vehicles to medical equipment.
