sapphire

sapphire (sapphire) has some unique application characteristics in the photoelectric field, which makes it one of the ideal materials for many optical and electronic devices:

1. Hardness and wear resistance Sapphire is a very hard material. Its Mohs hardness is 9, second only to diamond. This makes sapphire have excellent wear resistance and scratch resistance, which makes it outstanding in optical applications requiring long-term stability and durability.
2. Optical transparency Sapphire has a wide range of transparency, and the transparency is up to 95% in the visible light and near infrared spectrum. This makes sapphire an ideal choice for making high-quality optical windows, lenses and laser components.
3. Thermal conductivity Sapphire has high thermal conductivity, which enables it to effectively dissipate heat, which is particularly important for some high-power lasers and optoelectronic devices.
4. Chemical inertness : Sapphire has good stability and inertia to most chemicals, and is not vulnerable to chemical corrosion or oxidation, which makes its application in harsh environments more reliable.
5. optical performance : Sapphire has excellent optical properties, such as low self absorption, high refractive index and low dispersion, which make it widely used in high-performance optoelectronic devices such as lasers, optical fiber communications, optical sensors, etc.
6. Transparency stability : The transparency of sapphire changes little with the wavelength, so it has stable transparency in a wide spectral range and is suitable for various optical and photoelectric applications.
7. Electrical insulation Sapphire is a good electrical insulator and can be used for photoelectric devices requiring electrical insulation.
8. Radiation resistance Sapphire has good resistance to radiation, and is suitable for photoelectric equipment used in radiation environment.
9. dimensional stability : Sapphire has low thermal expansion coefficient and good dimensional stability, which is suitable for precision optical systems.

In general, the unique characteristics of sapphire in the photoelectric field include its hardness, transparency, thermal conductivity, chemical inertia and excellent optical properties, making it one of the preferred materials for many optical and electronic devices.
