TAOMSUN sapphire convex / hemisphere lenses are precision-machined from optical grade sapphire single crystal (α-Al₂O₃). With a Mohs hardness of 9 and a transmission range covering 0.17-5.5μm (UV to mid-infrared), sapphire offers extremely high surface hardness, chemical corrosion resistance, high temperature resistance and excellent thermal conductivity – the ideal choice for optical systems in demanding environments. Available in plano-convex, plano-concave, biconvex, meniscus and hemispherical forms; size, focal length and coating can be customized per drawing. Widely used in laser focusing, fiber coupling, imaging systems, endoscopes, sensors and laser aesthetic equipment.

🔍 Core features: 0.17–5.5 μm wide-band transmission – usable from UV to mid-infrared without coating; hardness second only to diamond for scratch and wear resistance; thermal conductivity as high as 27.21 W/(m·K), ideal for high heat-load laser applications.

Custom machining per customer drawings or specifications is supported:

• Size customization: diameter 0.3–200 mm; special-shaped lenses available
• Type customization: plano-convex, plano-concave, double-convex, meniscus or hemisphere
• Focal length customization: focal length designed to your application needs
• Coating customization: AR anti-reflection, beam-splitting or metal coatings available
• Small-batch trial orders: 5–10 pieces for trial validation

Q: What is the difference between sapphire lenses and ordinary optical glass lenses?
A: Sapphire lenses have a Mohs hardness of 9 (second only to diamond), resist scratching, chemical corrosion and high temperatures (melting point 2040℃), and offer excellent thermal conductivity. Ordinary optical glass is softer, easier to scratch and conducts heat poorly. Sapphire suits high-end applications such as laser systems and harsh environments; ordinary glass suits conventional optical systems.

Q: What is the transmission range of sapphire lenses?
A: Uncoated sapphire lenses transmit from 0.17–5.5 μm, covering the UV to mid-infrared bands. Coatings can be applied to optimize transmission for specific wavelength bands.

Q: Which lens types are available?
A: Plano-convex, plano-concave, double-convex, meniscus and hemisphere forms are available. Plano-convex lenses are used for focusing/collimating, double-convex for imaging systems, and hemisphere for fiber coupling and endoscopy.

Q: Can non-standard sizes and coatings be customized?
A: Yes. TAOMSUN supports diameter customization from 0.3–200 mm, as well as AR anti-reflection, beam-splitting and metal coatings. Please provide CAD drawings or specification requirements.

Q: Are sapphire lenses suitable for high-power laser applications?
A: Absolutely. Sapphire offers thermal conductivity as high as 27.21 W/(m·K) and a melting point of 2040℃, delivering excellent thermal stability – the ideal choice for high-power laser systems.
