SILICON ETALONS

HIGH INDEX ETALONS FOR THE INFRARED (NOTE: THE PATTERN ON THE ENDS IS JUST A REFLECTION...)

 

Solid Silicon Etalons

 

Solid silicon etalons are interesting because the high index of silicon (3.4 depending on wavelength) creates a reasonably high finesse without any coatings. The temperature sensitivity of silicon can also be useful (or problematic). These etalons are often used to monitor the wavelengths of long wavelength lasers.

 

 

  • Material: Silicon
  • Wavelength range: IR 1.2um to 6.3um
  • Wedge < 0.5 arc second*
  • Surface quality: 40/20 or better
  • Surface figure: λ/20
  • Mounting: the 8x8mm and 14x14mm etalons can be cemented to a 1" diameter holder
  • Finesse is ~2.5 dependent on the wavelength
  • Thickness: see table
  •  If your etalons require coatings then we can use our fluid jet polishing system to reduce the wedge and increase the finesse
  • We have two standard sizes for the silicon etalons
  • 8 x 8mm
  • 1" diameter
