Sapphire Optical Mirrors


Synthetic sapphire (Al2O3) is a single crystal form of corundum. It has excellent physical and optical properties. It is second only to Diamond monocrystals in nature.

Sapphire can be used as an optical mirror substrate material. Unlike conventional optical mirror substrates, it has a harder property, so it is resistant to shock, pressure, and scratch resistance.

Types of Sapphire Optical Mirrors

According to the shape, the typical types of sapphire optical mirrors are: planar mirrors (round, rectangular), planar convex mirror, cylindrical mirrors, etc.
  • Planar Mirrors: Round sapphire mirror, rectangular sapphire mirror, Elliptical Sapphire Mirror
  • Plano Convex Mirrors
  • Cylindrical Sapphire Mirrors
  • Customized sapphire mirrors: sapphire mirrors with holes

Depending on the nature of the reflective film, the typical types of sapphire optical mirrors are: metallic thin film sapphire mirrors, dielectric thin film sapphire mirrors, etc.

  • Metallic Thin Film
  • Dielectric Thin Film

Creator Optics can fabricate a variety of reflective coatings on sapphire substrates, such as metallic reflective coatings – Internally Reflective Aluminum, Internally Reflective Silver, Protective Aluminium, Protective Silver, Gold, Ehnhanced Gold, and high-reflection coatings in UV, VIS and IR wavebands.
