Product Overview
Our precision sapphire triangular plates are engineered for industrial applications demanding exceptional hardness, thermal stability, and chemical resistance. Made from 99.9% high-purity single-crystal Al₂O₃, these components feature a triangular shape with precision-machined through-holes, providing unmatched durability and optical clarity.
These plates are ideal for semiconductor processing, high-pressure viewing windows, optical alignment systems, and other environments where standard glass or ceramic materials fail.

Často kladené otázky (FAQ)
Q1: What is the minimum through-hole size you can produce?
Holes as small as 0.2 mm with ±0.01 mm tolerance can be precisely drilled using ultrasonic or laser machining, ensuring smooth, chipping-free walls.
Q2: Can the triangular shape and hole placement be customized?
Yes. We support full customization of triangle types (equilateral, right-angle, etc.) and hole positions. CAD, STEP, or PDF drawings can be submitted for feasibility review.
Q3: How is surface quality and flatness guaranteed?
All components undergo interferometer and optical comparator inspection. We ensure Scratch/Dig 20/10 (MIL-PRF-13830) and λ/10 @633 nm flatness, suitable for high-precision optical paths.
Q4: Why choose sapphire over quartz or alumina ceramics?
Sapphire provides superior mechanical hardness, thermal resistance, chemical and plasma durability, and wide optical transmission, making it the best choice for demanding industrial conditions.
Q5: Can you handle designs beyond standard specifications?
Yes. We often work on advanced R&D projects and can provide solutions for non-standard geometries or extreme requirements. Please contact us for consultation.
