TAOMSUN sapphire convex lens/semi-circular lensadoptOptical grade sapphire single crystal (α - Al ₂ O ∝)Made by precision machining, with a hardness of Mohs 9, second only to diamond, and a transmission range covering0.17-5.5μm(UV to mid infrared). Sapphire material has extremely high surface hardness, chemical corrosion resistance, high temperature resistance, and good thermal conductivity, making it an ideal choice for optical systems in harsh environments. Lens types includeFlat convex, flat concave, double convex, crescent shaped, hemisphericalVarious forms, sizes, focal lengths, and coatings can be customized according to the drawings.
🔍 Core features:A wide wavelength range of 0.17-5.5 μ m can be covered from ultraviolet to mid infrared through uncoated materials. Its hardness is second only to diamond, and it is scratch resistant and wear-resistant. Its thermal conductivity is as high as 27.21 W/(m · K), making it suitable for high heat load laser applications.

Support customization based on customer provided drawings or specifications:
Q: What is the difference between sapphire lenses and ordinary optical glass lenses?
A: Sapphire lenses have a Mohs 9 hardness (second only to diamond), are resistant to scratches, chemical corrosion, and high temperatures (melting point 2040 ℃), and have excellent thermal conductivity. Ordinary optical glass has low hardness, is prone to scratches, and has poor thermal conductivity. Sapphire is suitable for high-end applications such as laser systems and harsh environments, while ordinary glass is suitable for conventional optical systems.
Q: What is the transmission range of sapphire lens?
A: In the uncoated state, the transmission range of sapphire lens is 0.17-5.5 μ m, covering the ultraviolet to mid infrared wavelength range. Combined with coating, the transmittance can be optimized for specific frequency bands.
Q: What types of lenses can be selected?
A: It can provide various forms such as flat convex, flat concave, double convex, crescent shaped, hemispherical, etc. Flat convex is used for focusing/collimation, biconvex is used for imaging systems, and hemispherical is used for fiber coupling and endoscopes.
Q: Can non-standard sizes and coatings be customized?
A: Okay. TAOMSUN supports customization of sizes ranging from 0.3-200mm in diameter, as well as customization of coatings such as AR anti reflective film, spectral film, and metal film. Please provide CAD drawings or specification requirements.
Q: Is sapphire lens suitable for high-power laser applications?
A: Very suitable. Sapphire has a thermal conductivity of up to 27.21 W/(m · K), a melting point of 2040 ℃, and excellent thermal stability, making it an ideal choice for high-power laser systems.
