Used Japanese Optorun OTFC1550 Vacuum Coating Machine, suitable for coating IR cut filters/optical filters.

I. Basic Configuration Vacuum Chamber Dimensions: Ф1550×1800mm, made of SUS304 stainless steel, featuring high corrosion resistance and sealing performance. Workpiece Holder: Diameter Ф1400mm, rotation speed adjustable from 10-30rpm, supports uniform coating for various types of substrates. RF Source and Evaporation Source Equipped with a 23-inch RF ion source (RF ion source), which enhances film density and abrasion resistance through high-density ion current (passing 40,000 abrasion tests). The evaporation system adopts dual electron guns (Model 16F), paired with a 12-pocket ring crucible and thermal resistance evaporation device, supporting complex multilayer coating (over 100 layers). Exhaust System Combination design: Mechanical pump (Model 275/SV630) + Roots pump (Edwards brand) + diffusion pump and cryogenic condenser (POLYCOLD), with an ultimate vacuum ≤7.0×10⁻⁵Pa, achieving working vacuum in just 15 minutes. Film Thickness Monitoring Integrated HOM2R-VIS350A optical film thickness monitor, wavelength range 350-1100nm, paired with a 6-point crystal sensor and crystal control system, achieving nanoscale precision control. 

II. Technical Parameters Vacuum Performance: Ultimate vacuum ≤7.0×10⁻⁵Pa, pumping time ≤15 minutes. Coating Layers: Supports complex coating processes with over 100 layers. Electron Gun Configuration: Dual electron guns (Japanese Electronics Model 16F), supporting multi-point and ring crucibles. Sensor System: XTC/3 + 6-point crystal sensor, real-time monitoring of the coating process. 

III. Application Areas Optical Films: Including AR film (anti-reflective film), AF film (anti-fingerprint film), and AS film (anti-smudge film). Industrial Applications: Suitable for coating needs in optical devices, touch screens, lenses, display panels, and other fields.

 IV. After-Sales Service Provides installation and debugging, process training, and equipment maintenance support. Equipment supports leasing or purchase, offering flexible options based on needs. 

V. Equipment Advantages High Precision: Combines optical monitoring and crystal control systems to ensure film uniformity. High Efficiency and Stability: Dual electron guns and RF ion source combination enhance coating efficiency and film durability. Modular Design: Vacuum chamber, exhaust system, and other components can be expanded or adjusted according to process requirements.
