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 application of the coating technology of vacuum coating equipment to optical lenses, the earliest lenses did not have optical coating, and some even did not have the matting inside the lens barrel and the blackening of the edge of the lens, and then a single-layer coating appeared, but this was mainly used In military telescopes, it is used to achieve lens extinction and reduce the possibility of being discovered by the enemy (for example, Zeiss's T* coating was first developed for military use). In the field of civilian cameras, 1941 Kodak produced the first coated lens Camera Ektra, but the great development of coating technology should be counted from Pentax's SMC-coated too bad horse lens in the early 1970s.

The coating on modern lenses can be divided into two types. One is called antireflection coating, which increases the light transmittance, while the other coating changes the color spectrum transmission characteristics of the lens, such as a lens. Although the refractive index and other indicators of the optical material used in a certain lens are very good, but there is a yellowish phenomenon, then coat it with a spectrum blocking film to correct the color cast back (the three princesses of Pentax use high refraction Glass, so it is slightly yellowish), and now the development of coating technology can compensate for the shortcomings of some relatively cheap optical materials. The design of the lens no longer needs to use expensive special formula optical glass to complete as in the past, so the new In general, the lens of each lens has a multi-layer coating on the air contact surface, which also highlights the important role of the coating on the lens from another aspect.

When many people wear glasses, they require a film on the lenses. There are two main types of lens coating: one is anti-reflective coating, which means that by coating the front surface of the lens with multiple layers of transparent materials with different refractive indexes and different thicknesses, the principle of light interference is used to reduce the excess reflected light on the lens surface. After the anti-reflective film is added to the lens, the light permeability will increase, the wearer feels that the glare is reduced, and the vision is more real and bright. The other is hard coating, which is mainly used for resin lenses. It is generally added on the front surface of the lens to enhance the abrasion resistance of the resin lens and at the same time enhance the light permeability. When cleaning the hard-coated lens, the user should first wash the front and back surfaces of the lens with clean water, and then blot it dry with a clean soft cloth. Be careful not to wipe the lens when it is dry. If the ordinary lens can be seen clearly, there is no need to add a film. If you want to add it, the resin lens can be added with an anti-reflective film or a hard film. The glass lens generally only has an anti-reflective film. Anti-reflective film and hardened film are a kind of optical film layer coated by optical vacuum coating equipment.
