What it is
The OTFC 1550 is an optical thin film coater model from Optorun. The vacuum chamber is constructed from SUS304 stainless steel with a diameter of 1550 millimeters and a height of 1800 millimeters. The substrate dome has a diameter of 1400 millimeters. The substrate dome rotation speed is variable from 10 rpm to 30 rpm. The system achieves an ultimate pressure of 7.0 × 10⁻⁵ Pa or lower. Pump-down time from atmosphere to 1.3 × 10⁻³ Pa is 15 minutes. The substrate heater can reach a maximum temperature of 350 °C. The machine’s approximate external dimensions are 5500 millimeters width, 7200 millimeters depth, and 3700 millimeters height. The approximate gross weight is 10000 kilograms. Power requirement is three-phase, 200 volts, 50/60 Hz, 120 kVA. Cooling water flow rate is 180 liters per minute or greater. Compressed air pressure requirement is 0.5 MPa or greater.[3]
How it works
General reference — not yet source-verifiedOptical thin film coaters operate under high vacuum by evaporating or sputtering coating materials onto a substrate. A typical system uses electron beam evaporation sources to vaporize materials, while an ion source bombards the growing film to improve density and adhesion in a process known as ion-assisted deposition. An optical thickness monitor continuously measures the reflectance or transmittance of the film to control layer thickness precisely.
Where it fits in the process flow
General reference — not yet source-verifiedOptical thin film coaters are used in the fabrication of precision optics, typically after the lenses, mirrors, or other optical elements have been ground, polished, and cleaned. The coating process adds thin-film layers that modify the optical properties of the surface. Coated optics then proceed to assembly or further inspection steps.
Applications
The OTFC 1550 is suitable for producing anti-reflection coatings and optical filters including edge filters and band pass filters. The system can deposit over 100 layers, enabling complex multilayer designs.[3]
