Sapphire custom made optics Physix

High-durability optics for demanding UV, visible and infrared applications

Sapphire Optics

Sapphire is an exceptionally hard and durable optical material with excellent mechanical strength, chemical resistance and thermal stability. Combined with its broad optical transmission range, these properties make sapphire an excellent choice for optical windows, protective covers, lenses and other components used in harsh environments.

Why use sapphire for optical components?

Sapphire is a single-crystal form of aluminium oxide (Al₂O₃). It combines optical transparency with exceptional mechanical and thermal properties.

Key advantages include:

  • Extremely high surface hardness
  • Excellent scratch and abrasion resistance
  • High mechanical strength
  • Excellent chemical resistance
  • High operating temperature capability
  • Good thermal conductivity
  • Broad optical transmission from UV into the infrared
  • Excellent resistance to harsh environments
  • Good electrical insulation properties
  • Long-term dimensional stability
