Silicon custom made optics

Custom silicon optics for infrared imaging, sensing and laser applications

Silicon Optics

Silicon (Si) is a widely used optical material for near-infrared and mid-wave infrared applications. Its combination of good infrared transmission, high refractive index, low density, excellent thermal conductivity and strong mechanical properties makes silicon attractive for lenses, windows and other precision IR optical components.

Physix supplies custom silicon optics manufactured according to customer drawings and optical specifications. Components can be produced in a wide range of geometries and dimensions and supplied with optical coatings optimized for the required infrared wavelength range.

Why use silicon for infrared optics?

Silicon is a crystalline semiconductor material with several properties that make it particularly useful in infrared optical systems.

Key advantages include:

  • Good transmission in the near- and mid-infrared
  • High refractive index
  • Low density compared with germanium
  • Excellent thermal conductivity
  • Good mechanical strength
  • High material hardness
  • Low optical dispersion
  • Suitable for precision lenses and windows
  • Suitable for compact infrared optical systems
  • Compatible with high-performance infrared coatings
