Custom Sapphire Triangular Component with High-Precision
Through-Hole
Product Introduction
Our Custom Sapphire Triangular Components are engineered for
high-end industrial applications requiring extreme mechanical
strength, thermal stability, and chemical resistance. Manufactured
from 99.9% high-purity single-crystal sapphire (Al₂O₃), these
components feature a unique triangular geometry with
precision-drilled through-holes.
This product is ideal for applications such as semiconductor wafer
handling, high-pressure viewports, and optical sensors, where
standard glass or ceramics cannot meet performance requirements.

Frequently Asked Questions (FAQ)
Q1: What is the smallest hole diameter you can achieve in a
sapphire triangular component?
We can precisely machine holes down to 0.2 mm with a tolerance of ±0.01 mm using advanced ultrasonic or laser drilling. The resulting hole
walls are smooth and free of chipping.
Q2: Can the triangular shape and hole positions be customized?
Yes. We offer full customization of triangle geometry (equilateral,
right-angle, or other types) and exact hole locations. CAD, STEP,
or PDF drawings can be submitted for feasibility evaluation.
Q3: How do you ensure high surface quality and flatness?
Each component undergoes rigorous inspection using interferometers
and optical comparators. We guarantee Scratch/Dig 20/10 per MIL-PRF-13830 standard and surface flatness up to λ/10 @633 nm, suitable for high-precision optical paths.
Q4: Why choose sapphire over fused quartz or alumina ceramics?
Sapphire provides superior mechanical hardness, thermal resistance, plasma and chemical
durability, and broad optical transmission, making it ideal for extreme conditions where other materials
fail.
Q5: What if my design exceeds standard specifications?
We frequently work on R&D and custom projects with challenging geometries. If your design falls outside listed parameters, please contact us
— we can often provide solutions for unique or "impossible"
requirements.
