Sapphire Custom-shaped Optical Windows Product Overview

Sapphire Custom-shaped Optical Windows Optical Components

Sapphire irregular optical windows are precision-machined optical components fabricated from high-purity single-crystal aluminum oxide (α-Al₂O₃). Their core advantage lies in combining sapphire's inherent material properties with custom geometric designs to meet extreme environmental demands for optical, mechanical, and chemical performance.

Company Service Highlights:

Full-size Customization: Supports circular, square, annular, and complex irregular shapes (e.g., trapezoidal, hexagonal), with thickness tolerance of ±0.01 mm and maximum diameter up to 500 mm.
Multi-Material Integration: Offers standard sapphire wafers, tubes, rods, and hybrid structures (e.g., tungsten-copper encapsulation) alongside multi-layer coating solutions.
Rapid Delivery: From design to mass production in 2–4 weeks, accommodating small-batch prototypes and large-scale manufacturing.
