The scia Opto 300 is used for uniform coating of precision optics. With up to 6 targets for flexible multilayer deposition, even a mixing of target materials is possible. Two loading positions allow continuous and fully automatic processing of the substrates. Optical in-situ monitoring with integrated test glass changer ensures highest precision and optimized uniformity of coating.
- Variable substrate sizes up to 300 mm dia.
- Automatic loading with two loading positions for continuous processing
- Up to 6 target materials on a rotatable trum, each target up to 300 mm x 300 mm, with optimized geometry for mixed layers or smooth transition between layers
- Excellent process uniformity by substrate rotation with up to 60 rpm
- In-situ optical thickness monitor (OTM) and test glass changer
- Optimized geometry for coating with low stress
- Dielectric mirrors (e.g. rugate filters)
- Optical coatings for high- and anti-reflective layers, bandpass and notch filters
- High laser damage threshold coatings
- Deposition of refractive index gradient layers
- In-situ preprocessing of substrates (etching, cleaning, smoothing)
- Metallic, seed and protective coatings
- Primary source sputters material from a target to the facedown oriented substrate
- Secondary source used for pre-cleaning the substrate and / or assist during deposition
Ion Beam Sputtering (IBS) thereby material is sputtered from a target with an ion beam and is deposited on the substrate.
Dual Ion Beam Sputtering (DIBS) uses an additional assist ion beam source to influence the growing film.
