Combination of Advanced Equipment and Fine Management

Nanjing Apex Optics Ensures the Quality of Coated Products

Optical coating is a key link in the production of optical components, and its process level directly affects product performance. Nanjing Apex Optics Co., Ltd. is equipped with industry-leading coating equipment and supporting systems, combined with standardized production management, to build a stable and efficient coating production system to ensure product quality.

The company's coating workshop has 5 sets of equipment, with film thickness control accuracy up to ±0.1nm and large-area coating uniformity error less than 1%. In terms of supporting systems, 3 ultrasonic cleaning machines adopt the "multi-frequency alternating cleaning" process, which ensures the cleanliness of components through laser interferometer detection, and controls the incidence of coating pinhole problems below 0.1%. The company has customized more than 200 sets of tooling fixtures, which are suitable for various components. The rotating fixture designed for large-size aspheric mirrors controls the coating uniformity error within 1.5%.

The company has established a "process parameter database + intelligent monitoring system", storing more than 500 sets of parameters to shorten the process development cycle. The quality inspection link is equipped with a variety of equipment to improve the production capacity of large-size and high-damage threshold products.
