Product Specification

Custom Sapphire Through-Hole Plate (Shaped Multi-Hole Sapphire Window)

Scratch-resistant · High optical clarity · Heat & chemical resistant · Made to your drawings

This product is a custom-machined single-crystal sapphire (Al₂O₃) plate featuring shaped outer profiles and multiple through-holes (e.g., 3-hole mounting/locating patterns). It’s ideal for optical protection, precision assemblies, and transparent isolation parts used in harsh environments.

Key Benefits

• Exceptional scratch & wear resistance
  Sapphire’s extreme hardness helps maintain surface quality during long-term use, cleaning, and abrasion.

​

• High transmission, low haze (optical polishing available)
  Suitable for windows, protective covers, viewing ports, and sensor apertures.

​

• High temperature & chemical resistance
  Performs reliably in elevated temperatures and aggressive chemical environments (case-by-case evaluation).

​

• Dimensional stability & low outgassing
  Well-suited for precision instruments, vacuum systems, and clean environments.

​

• Controlled hole edges & reduced chipping risk
  Optional chamfer/radius, edge finishing, and deburring help reduce stress concentration during assembly.

​

• Prototype to production support
  Fast sampling and stable quality for scaling to volume.

FAQ

Q1: Why sapphire instead of glass or quartz?
A: Sapphire offers superior scratch resistance and stronger mechanical/thermal/chemical durability—ideal for demanding windows and wear parts.

Q2: Will the holes chip easily?
A: Proper edge control (chamfer/radius), deburring, and assembly-oriented design significantly reduce chipping risk. We can also recommend processing options based on your mounting method.

Q3: Can you apply optical coatings?
A: Yes. Tell us the wavelength range (visible/NIR, etc.), incident angle, and target performance—we’ll match a coating solution.
