Siliciumbearbeitung Andrea Holm supplies parts for IR-Optics as well as Laser – and X-Ray Optics


For IR-Optic we supply blanks for lenses, pre-shaped lenses and domes (ready to be polished) or round and rectangular plates and discs.

  • Diameter up to 700 mm possible
  • Pre-shaped domes and lenses (ready to be polished)
  • Polished flat discs and plates
  • Dia.:20 Ohmxcm (best IR material, but limited in Diameter)
  • Dia.: > 200 mm: CZ, n/Phosphorus, > 20 Ohmxcm with additional tempering process
    to increase transmission rate
  • To guaranty optical properties (>52% at 3-5µm) Transmission rate is measured


Other infrared material:

  • Sapphire
  • Germanium

SPECIAL-OPTICS for Laser and X-Ray applications

Channel-Cut, Mono- and Polychromator

Channel-Cuts are very unique optics. We have developed a technique to be able to polish the optical surfaces without destroying the atomic layer. We can adjust orientation accuracy to </=0,01°
