Features


  • Wide Variety of Mirrors: Photonchina offers an extensive range of mirrors including laser line mirrors, harmonic separator mirrors, high reflection (HR) mirrors, partial reflection mirrors, and metallic coated mirrors.

  • Customizable Shapes and Surfaces: Choose from rectangular, round, elliptical, or custom shapes with flat, spherical concave or convex, and cylindrical surfaces.

  • Optimized HR Laser Line Mirrors: HR mirrors are designed for optimized performance at specific wavelengths and angles of incidence (AOI), ensuring very high reflectivity.

  • Advanced Coating Techniques: Coatings are applied using ion beam sputtering (IBS) or electron beam evaporation, with or without ion assistance, for superior performance.

  • High Reflectivity: HR laser line coatings reflect a wavelength range of less than 10% of the central wavelength (CWL), e.g., HR @ 800 nm reflects 760-840 nm.

  • Custom Coatings Available: Tailored coatings can be provided for any wavelength within the range of 0.19 - 20 μm.

  • Mass Production Capabilities: Photonchina can produce up to 5000 pieces per month, accommodating large-scale needs.

  • Premium and Standard Capabilities:

    • Substrate Materials: Options include BK7 and Fused Silica.

    • Diameter Tolerance: Premium: +0.0, -0.1mm; Standard: +0.0, -0.2mm.
