Optical PVD Coating Machine 200nm 25000nm Quartz Crystal Controller

Customized Optical PVD Coating Machine For Sale

1. Product Description:

The Optical Coating Systems manufactured by Guotai are designed to maximize coating uniformity and production throughput, and have supported to a wide range of coating applications to include anti-reflection and highly reflective coatings, edge filters, beam splitters, optical filters, laser diodes, polarizers, gain flattening filters, and other complex non-quarter wave design including low stress and high laser damage threshold coatings.

2. Main Features:

• Flexible Configuration

The system can be carefully tailored to support client’s specific coating application and production requirements. Chamber sizes ranges from 400mm to 2700mm, which can be used as laboratory or mass production equipment. Configuration options include Thermal Evaporation, Electron Beam Evaporation, and Electron Beam Evaporation with Ion Assist; Substrate fixturing is available in single rotation, planetary, calotte, flip planetary, and unique arrangement for specific requirements; Support front side heating or back side heating, or both.

• Excellent Performance and Reliability

Guotai recognizes that user-friendliness and reliability of optical coating equipment is paramount to client’s success. The system incorporates proven design features based on decades of experience that produce exceptional results with easy to use software and dependable run to run consistency. We strive to continuously obtain customer feedback from coating engineers, operators, and maintenance personnel to improve design features that will minimize system downtime and increase overall productivity. Subsystem equipment of our systems are from reliable and brand manufacturers such as Baosi, Edwards, Inficon, Burkert, Omron to name a few. This allows our clients to benefit from the depths of Guotai and its vendors for the availability of service and spare parts.

• Coating Process Capability and Support

The system includes optional process development, system calibration, film characterization and uniformity adjustment to less than 0.5%. They can be delivered with multiple, fully developed, production-ready coating processes, pre-programmed to minimize system downtime between production changeover's and to maximize run efficiencies and product yields. Calibration of the process is so consistent that new designs may be supplier to the operator from a remote site with the results from a test run analyzed and a small adjustment in calibration made before final production. Designed for run-to-run repeatability and to deliver excellent results after a minimum number of test coatings, the system lends itself to a fully automatic operation reducing time, manpower, and costs-even with high layer counts and complex layer stacks.

[The history of vacuum evaporation]: Michael FaradayZui put forward the basic principle early in 1857, and then, in the 1930s, due to the practical use of oil diffusion vacuum pumps, evaporation was mainly used to make anti-reflection films for lenses. During the Second World War, the demand for materials for other optical machines increased, and vacuum evaporation also developed rapidly.

[Principle of vacuum evaporation]: In a vacuum state, heating the target material in the evaporation container to make atoms or molecules escape and deposit on the surface of the target object to form a solid film. According to the types of evaporation materials and substrates, it can be divided into heating methods such as resistance heating, electron beam, high-frequency induction, and laser. Evaporation materials include metal materials such as aluminum, leaded, gold, silver, platinum, nickel, and materials that can produce thin films with optical properties, and mainly use oxides and fluorides such as SiO2, TiO2, ZrO2, and MgF2. In addition to metal, resin and glass can also be used for vapor deposition. In recent years, even paper has become vapor-depositable.

[Advantages and disadvantages of evaporation coating]:
Advantages: The equipment is simple and easy to operate; the film formation rate is fast and the efficiency is high.
Disadvantages: the thickness uniformity of the film is not easy to control, the evaporation container has the hidden danger of pollution, the process repeatability is not good, and the adhesion is not high.
