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

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.
