Sapphire square block


He Rui optics' Uncoated sapphire provides exceptional surface hardness and a transmission range extending from the UV to the MIR. It can only be scratched by a few materials other than itself. The uncoated substrate is chemically inert and insoluble to water, common acids, or alkalis at temperatures up to ~1,000 °C.

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.

Uncoated Wavelength Range: 200 nm - 4.5 µm

 with AR Coating for 1.65 µm - 3.0 µm or 2.0 µm - 5.0 µm on Both Sides

Stable Performance over a Wide Temperature Range
