Abstract

Synthetic sapphire prisms are manufactured using high-purity aluminum oxide (α-Al₂O₃) through advanced crystal growth techniques such as the ​Kyropoulos method.

Key advantages include:

• ​Exceptional Physical Properties:

Mohs hardness of ​9, second only to diamond, with a dry friction coefficient of ​0.14​ against steel.
High-temperature resistance (melting point: 2050°C) and chemical stability, resistant to acid/alkali corrosion.
 

• ​Superior Optical Performance:

Broadband transmittance over ​90%​ across ​170nm–6000nm, with a refractive index of ​1.76, suitable for UV, visible, and IR optical systems.
Surface roughness as low as ​0.1μm, enabling precise beam control.
 

• ​Customizable Specifications:

Customizable sizes (5–300mm edge length) with tight tolerances (±0.02mm linear, 20''–10' angular).
Special designs: planar/curved surfaces, oil grooves, or drilled holes.

Sapphire Prism FAQ

Q: How do sapphire prisms perform optically compared to glass prisms?

A: Broadband transparency: Transmit ​>90% light​ across a wide spectral range (170nm–6000nm), covering UV, visible, and infrared wavelengths.
​High refractive index: ​1.76​ refractive index enables precise light bending and beam control, critical for lasers and imaging systems.
​Surface precision: Achieve ​surface roughness ≤0.1μm​ (or even ​0.012μm​ with polishing), minimizing light scattering.

Q: Can sapphire prisms be customized for specific needs?

A: Yes. We can offer :​

Size flexibility: Prisms with edge lengths from ​5mm to 300mm, with tight tolerances (±0.02mm linear, 20'' angular);
​Special designs: Options include curved surfaces, drilled holes, or oil grooves;
​Coatings: Anti-reflective (AR) or scratch-resistant coatings to enhance performance.

Q: How to maintain sapphire prisms?

A: Cleaning: Use lint-free cloths and mild solvents (e.g., isopropyl alcohol) to avoid surface contamination.
​Handling: Avoid direct contact with harder materials (e.g., diamond tools) or abrasive surfaces.
​Storage: Keep in protective cases to prevent accidental impacts.
