Machine Brief Description

The magnetron sputtering optical coating equipment is a high-precision, high-efficiency system widely adapted to the preparation of optical thin films and AF films, specifically for the surface treatment of optical components.

It adopts magnetron sputtering technology to sputter target atoms onto the substrate surface under a vacuum environment to form a uniform and dense film layer. It is widely used in the manufacture and processing of optical lenses, optical filters, laser equipment, and other high-end optical products.

Key Advantages & Features

Compared with the traditional evaporative optical coating machine, this new model offers a number of significant advantages. It has a large effective coating area, large loading capacity, higher efficiency, a stable process, good repeatability and stability, and good film bonding.
The coating process is based on reaction sputtering, utilising multiple sets of plane or rotating sputtering cathodes and a DC or medium frequency sputtering power supply.
The system is suitable for plating multi-layer optical films, and the addition of an evaporation coating device enables AF film plating to be achieved.
High-precision coating: precise control of sputtering parameters enables the deposition of a nanometre-thick film, ensuring the high performance of optical components.
Multi-layer coating: enables the deposition of multi-layer film systems, meeting the requirements of a variety of optical components, including transmittance enhancement film, reflective film, filter film and more.
