What is an Optical Sapphire?
Optical sapphire is not a natural gemstone; instead, it is a pure, single-crystal form of aluminum oxide (Al₂O₃) that is synthesized through artificial methods.
- It has the same composition as natural sapphire, but due to its extremely high purity, it possesses unparalleled comprehensive properties.
- Its most notable feature is its extremely high hardness, with a Mohs hardness of 9, only slightly lower than that of diamond. This means it is extremely scratch-resistant and cannot be damaged by daily dust and sand.
- At the same time, it has excellent optical properties, with a wide light transmission range, from ultraviolet to infrared, all with high light transmittance, ensuring clear and true imaging.
- In addition, it also has the advantages of high mechanical strength, good thermal stability and stable chemical properties.
What is an Typical application for Optical Sapphire?
Due to its extremely excellent optical and physical properties, optics is widely applied in high-end watch lenses, smartphone camera covers and screens, industrial optical windows, medical equipment and other high-tech fields.
What’a advantage to apply sapphire block in IPL hair removal device?
Optical beauty devices, especially high-end ones, widely use optical sapphire as the material for the contact head or the light-emitting window. The main reasons are as follows:
- Ensuring phototherapy efficacy: The high light transmittance ensures that the light waves precisely reach the target area.
- Enhance treatment safety: Excellent thermal conductivity ensures effective cooling and protects the epidermis.
- Ensure the durability of the instrument: The extremely high hardness ensures that the instrument remains in excellent condition over time.
- Optimize user experience: Soft to the touch, comfortable and hygienic.
Therefore, the application of sapphire materials is an important technical hallmark for high-end beauty devices to achieve high efficiency, safety and durability.
