Brief: In this video, we showcase the high-precision Custom Sapphire Square Plate with double-side optical polishing, highlighting its exceptional material properties and diverse industrial applications. You'll see how its superior optical clarity, mechanical strength, and thermal stability make it ideal for laser systems, scientific instruments, and harsh-environment observation windows.
Related Product Features:
  • Double-side optical polishing ensures mirror-grade surface roughness (Ra < 1 nm) for precise light transmission.
  • Exceptional flatness (up to λ/20) and parallelism (≤0.005 mm) for high-accuracy optical applications.
  • Ultra-wide spectral transmission from 150 nm (UV) to 5.5 μm (IR) for multi-spectral use.
  • High mechanical strength and abrasion resistance for durability in demanding environments.
  • Superior chemical stability, resistant to acids, alkalis, and solvents.
  • Thermal stability up to 1600°C, ideal for high-temperature applications.
  • Fully customizable in dimensions, thickness, orientation, and coatings (AR, AF, IR).
  • Widely used in laser systems, semiconductor equipment, and scientific instruments.
Faqs:
  • What are the advantages of double-side polished sapphire over single-side polished?
    Double-side polished sapphire offers higher symmetry, better parallelism, improved flatness, and superior optical uniformity, making it ideal for high-precision optical systems.
  • What is the thinnest sapphire square plate you can manufacture?
    We can produce plates as thin as 0.20 mm, depending on the size and application requirements.
  • Are custom coatings available for the sapphire plates?
    Yes, we offer various coatings including AR (anti-reflective), AF (anti-fingerprint), IR, and metal films to meet specific application needs.
