OTFC-1300 Optical Thin Film Coater

Product Description

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.

Key Features

    • 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.
