Gemstone step windows are double-plane circular or rectangular optical sapphire glass with a step surface for use with flanges or other concealed mountings, and are typically used as protective windows for sensors and detectors. The windows do not change the magnification of the system. Uncoated sapphire has excellent surface hardness and a transmission range extending from the UV to the mid-IR wavelength region. Sapphire can only be scratched by a few substances other than it. The uncoated substrate is chemically inert and is also insoluble in water, common acids or bases at temperatures up to about 1000°C.

Product features
High hardness: Sapphire is the material with the second highest hardness after diamond in nature. It has extremely high hardness and wear resistance, and can protect internal optical components from scratches and wear.
High temperature resistance: Sapphire has an extremely high melting point and can maintain stability in high temperature environments, making it suitable for high temperature industrial environments.
Corrosion resistance: Sapphire has good chemical stability and is not easy to react with chemicals such as acids and alkalis, and can resist harsh chemical environments.
High light transmittance: Sapphire has a wide light transmittance range from ultraviolet to infrared bands and can transmit light of various wavelengths.
Good insulation performance: Sapphire is an electrical insulator that can prevent electrostatic interference.
Advantages of sapphire step optical windows
