Sapphire window panels, as a high-performance optical component, have been widely used in many fields due to their excellent physical and chemical properties. Due to the diversity of its application scenarios, it has different names and uses in different industries. The following will introduce the names and characteristics of sapphire window plates in different application scenarios.

1. Sapphire protective window panel

In optical instruments and precision equipment, it is often used as a protective window to prevent dust, water vapor, or other pollutants from entering the interior of the equipment. The high hardness and scratch resistance of sapphire make it an ideal choice for protecting sensitive optical components. For example, in laser equipment, high-precision sensors, and microscopes, sapphire protective window plates can effectively extend the service life of the equipment while maintaining the stability of optical performance.

2. Sapphire optical window panel

In optical systems, it is often used as an optical window due to its excellent transparency and low absorption rate. Sapphire has high transmittance in the ultraviolet to infrared wavelength range (approximately 150nm to 5500nm), making it widely used in spectrometers, lasers, and infrared imaging devices. Sapphire optical window panels can withstand high temperature and high pressure environments, making them suitable for optical experiments and industrial applications under extreme conditions.

3. Sapphire observation window

Sapphire window plates are often used as observation windows in vacuum or high-pressure environments, and their high mechanical strength and chemical inertness make them materials for these applications. For example, in semiconductor manufacturing equipment, vacuum coating machines, and high-pressure reactors, sapphire observation windows can provide a clear view while withstanding pressure changes in extreme environments.

4. Sapphire laser window plate

In the field of laser technology, it is widely used as a laser window due to its high damage threshold and excellent thermal stability. Sapphire can withstand high-power laser irradiation without being easily damaged, so sapphire laser window plates are important components in laser cutting, laser marking, and laser medical equipment. Its high thermal conductivity can effectively disperse the heat generated by the laser and prevent the window plate from cracking due to thermal stress.

5. Sapphire infrared window panel

Sapphire infrared window panels not only provide clear imaging effects, but also maintain stable performance in harsh environments. In infrared optical systems, sapphire window plates are often used as infrared window plates due to their excellent transmission performance in the infrared band. Sapphire has a high transmittance for mid to far infrared light (3-5 μ m band), and is therefore widely used in thermal imagers and infrared detectors.

6. Sapphire UV window panel

In ultraviolet optical applications, it is often used as a UV window due to its high transmittance to ultraviolet light. Sapphire has superior transmission performance in the ultraviolet band (approximately 150-400nm) compared to many other optical materials, making it an important optical component in UV spectrometers, UV lasers, and UV disinfection equipment.

7. Sapphire corrosion-resistant window panel

In the chemical industry, due to its corrosion resistance, it is often used as a corrosion-resistant window plate. Sapphire has extremely high resistance to most acids, bases, and organic solvents. Therefore, in chemical reaction vessels, chemical pipelines, and corrosive gas detection equipment, sapphire corrosion-resistant window plates can work stably for a long time, avoiding equipment damage caused by corrosion.

8. Sapphire high-temperature window panel

In high-temperature environments, it is often used as a high-temperature window plate due to its high melting point and excellent thermal stability. Sapphire has a melting point of 2053 ℃ and can be used for a long time in high temperature environments above 1000 ℃ without deformation or failure. Therefore, sapphire high-temperature window plates are an ideal choice in high-temperature furnaces, aircraft engine testing equipment, and high-temperature sensors.

9. Sapphire medical window panel

In medical devices, it is often used as a medical window due to its biocompatibility and high transparency. For example, in endoscopes, laser surgical equipment, and medical sensors, sapphire window plates can provide a clear field of view and stable optical performance, while avoiding adverse reactions to patients.

10. Sapphire consumer electronics window panel

The high wear resistance of sapphire can effectively protect the screens and lenses of electronic devices, extending their service life. In consumer electronics, due to its high hardness and aesthetics, it is often used as a protective cover for mobile phone cameras, a window for smart watch screens, and fingerprint recognition modules.

Sapphire window panels have diverse names and uses in different application fields due to their unique physical and chemical properties. Whether as a protective window, optical window, or special window that is resistant to high temperatures and corrosion, sapphire window panels can provide high performance and reliability.
