The Optical Coating Systems manufactured by Guotai are 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 spliters, optical filters, laser diodes, polarizers, gain flattening filters, and other complex non-quarter wave design including low stress and high laser damage threhold coatings.
The system includes ZZS and GT series, Chamber sizes range from 600~2700mm, custom spces on request are available.
The system can be carefully tailored to support client’s specific coating application and production requirements. Configuration options include Thermal Evaporation, Electron Beam Evaporation, and Electron Beam with Ion Assist; Both Crystal and automated optical monitoring for high accuracy and tight coating specification are available; Substrate fixturing is available in single rotation, planetary, calotte, flip planetary, and unique arrangement for specific requirements; Support front side baking or back side baking, 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, Baodi, 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.
