Supplies and Polishing process

Supply

Podeo buys raw materials from selected and well known Suppliers. Each Supplier must send a certificate showing compatibility between their materials and CO2 laser application.

Podeo manage polishing process, and subcontract coatings through Partners with a long know-how in 10,6um wave length. Each Partner must supply a spectral run report with coated optics, showing transmission and absorption %.

Polishing process:

Focus lenses:

Material commonly used is ZnSe (Zinc Selenide).
Lenses are polished both sides.

Our tolerances are:

  • 0/-0,1mm on diameter
  • +/- 0,1mm on thickness
  • +/-0,5% on focal length

Total reflectors:

Material commonly used is Silicon or Copper.
Total reflectors are polished on 1 side.

Our tolerances are: 0/-0,1mm on diameter

  • +/- 0,1mm on thickness
  • λ/4 for flatness

Phase retarders:

Material commonly used is Silicon or Copper.
Phase retarders are polished on 1 side.

Our tolerances are:

  • 0/-0,1mm on diameter
  • +/- 0,1mm on thickness
  • λ/4 for flatness
