Product Overview<\/strong><\/h2>\n

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 Al\u2082O\u2083, these components feature a triangular shape with precision-machined through-holes, providing unmatched durability and optical clarity.<\/p>\n

These plates are ideal for semiconductor processing, high-pressure viewing windows, optical alignment systems, and other environments where standard glass or ceramic materials fail.<\/p>\n

        \u010casto kladen\u00e9 ot\u00e1zky (FAQ)<\/strong><\/h2>\n

        Q1: What is the minimum through-hole size you can produce?<\/strong>
        Holes as small as 0.2\u202fmm with \u00b10.01\u202fmm tolerance<\/strong> can be precisely drilled using ultrasonic or laser machining, ensuring smooth, chipping-free walls.<\/p>\n

        Q2: Can the triangular shape and hole placement be customized?<\/strong>
        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.<\/p>\n

        Q3: How is surface quality and flatness guaranteed?<\/strong>
        All components undergo interferometer and optical comparator inspection. We ensure Scratch\/Dig 20\/10<\/strong> (MIL-PRF-13830) and \u03bb\/10 @633\u202fnm flatness<\/strong>, suitable for high-precision optical paths.<\/p>\n

        Q4: Why choose sapphire over quartz or alumina ceramics?<\/strong>
        Sapphire provides superior mechanical hardness, thermal resistance, chemical and plasma durability<\/strong>, and wide optical transmission, making it the best choice for demanding industrial conditions.<\/p>\n

        Q5: Can you handle designs beyond standard specifications?<\/strong>
        Yes. We often work on advanced R&D projects and can provide solutions for non-standard geometries or extreme requirements<\/strong>. Please contact us for consultation.<\/p>","protected":false},"excerpt":{"rendered":"
