Thin Film Coating Design

To reach optimal combinations of layers fulfilling spectral requirements we use world best software: Mac Leod, TFCalc, Film Star, Mcalc, Film 2000, MatEdit, Code.

We use different direct or indirect optical monitoring and quartz crystal strategies to program vacuum machines.

Thin film coating

Our coating facilities contain unique combination of coating deposition systems.

• Coatings are based on oxide and fluoride technologies
• Materials: TiO₂, SiO₂, Al₂O₃,Ta₂O₅,Y₂O₃, MgF₂, YF₃, Al, Ag, ITO, Au, Inconel, Invar, etc.
• HOT and COLD substrate deposition
• Number of layers: 1 – 120
• Evaporation time: 2 – 17 hours
• Wave lengths: 193 nm – 1500 nm
• Working environment: Class-1000, Class-10000
• Over 40 vacuum chambers (some of them include the ion assisted technology)

Equipment

• Vacuum chambers: Balzers, Leybold, Dynavac
• Ion assisted technology vacuum chambers: Leybold, SyrusPro, Leybold APS 1100, Balzers 760 (Mark II IAD)

Testing devices

• Spectrophotometers PerkinElmer 950 (with URA or Optical table attachments)
• Specord, HP, other types of diode lasers and polarizators
• For UV we are able control spectral parameters quality by 266 nm lasers and polarizators
