Product Description

Sapphire Substrate (DSP) Overview

The Double Side Polished Sapphire Substrate (DSP) is fabricated from high-purity (>99.99%) single crystal aluminum oxide (Al₂O₃). With both sides precision polished to atomic-level smoothness (Ra < 0.3 nm), this material offers excellent optical transparency, mechanical strength, and thermal stability. It is widely used in optical windows, laser components, semiconductor epitaxy, and scientific research applications.
