OTFC series, based on the ion-assisted technology, are the most suitable coating system for producing AR coatings and optical filters such as edge filters, band pass filters etc.   •     Chamber size: φ 600mm-φ1800mm •     60-point optical thickness monitor. •     RF ion source achieving uniformed, larger ion beam distribution over a larger area at high ion current density. •     Over 100 layers can be deposited by 2 EB guns and multi-point crucible hearth or annular hearth. •     Auto-deposition control system for fully automated process. •     Center-driving or planetary substrate dome is selectable. •     Diffusion pumps plus Polycold or Cryo- pumps.
