Broadly Used Silicon Import parts optical Silicon Reflective Mirror lenses

  • Reflective Lenses
  • silicone reflective mirror
  • Custom laser optical glass reflective lens
  • Silicon Reflective lenses

  • OEM-customized optical mirrors fabricated from single-crystal Silicon (Si) — a lightweight, high-thermal-conductivity, mechanically robust infrared-compatible substrate — with protected Gold (standard for MWIR/LWIR), protected Silver (VIS–NIR enhanced), or broadband dielectric coating per application. 

    Si mirrors are the preferred choice for Mid-Wave Infrared (MWIR 3–5 µm) thermal imaging systems, high-power CO₂ or fiber laser beam steering (where low absorption is critical), 

    aerospace dome/seekers, and FLIR fold mirrors. Available as plane, spherical concave/convex, or off-axis configurations in diameters from 10 mm to 300 mm, with customizable surface flatness (λ/10–4λ), edge blackening, and mechanical mounting.
