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.
