Customized Glass Coating Machine For Optic Thin Films

1. Product Description:

Anti-reflection coating is an optical coating with a wide range of applications, widely used in daily life, industry, astronomy, military science, electronics and other fields. With the development of the electronics industry and computers, anti-glare and anti-static films for displays and computer video protection screens have become new application areas for anti-reflection films and have broad market prospects. They can not only effectively improve the conversion efficiency of the battery, but also improve the substrate Mechanical properties, electrical properties, optical properties and other physical and chemical properties.

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 optical film basically achieves its effect by interference. It is to plate one or more layers of dielectric film or metal film or dielectric film or dielectric film and metal film on the optical element or the independent substrate to change the characteristics of broadcast transmission. Therefore, when the wave travels in the film, changes such as projection, reflection, absorption, scattering, and phase shift will occur.
The light wave will change in the spectrum after passing through the film, so these changes will make the optical film at least have the following functions:

• Increase in reflection or decrease in penetration
• Reduction of reflection or increase of penetration
• Dual-color, polarized auroral light splitting effect
• Filtering function such as spectral bandpass or ring
• Luminous flux adjustment of radiator
• Photoelectric information storage and input
