光学镀膜

改进光学系统的反射行为或传输特性

例如滤光片、透镜、眼镜或镜子。

光学镀膜真空解决方案

生产眼镜、镜子和反射镜需要先进的技术,包括一些借助真空实现的技术。真空在其中起到重要作用的工艺是生产抗反射和抗刮擦的薄膜层。您对眼镜的特殊滤光片、红外和紫外滤光片可能习以为常,但是光学镀膜也有大量的科学应用。从科研显微镜到空间观测用的詹姆斯·韦伯望远镜,专用光学滤光镜无处不在。

Optical Coating

采用 PVD 的光学镀膜

Optical coatings entail a combination of many thin layers to create various reflection characteristics or layers that improve light conductivity. These layers are usually applied in batch coating systems in a process called “physical vapor deposition” (PVD) or evaporation processes, all of which take place under vacuum conditions in pressure ranges of 10-2 to 10-3 mbar.

Optical coating applications require precision systems that can maintain desired vacuum levels at stable values inside the vacuum chamber. Leybold offers all vacuum products required for these systems, including:

Backing pumps or “fore” vacuum

In the first stage of the process, ambient gases and humidity must be removed from the vacuum chamber with “roughing” pumps that can evacuate the vacuum chamber very quickly. We have various product families, depending on the exact requirements of your processes, including DRYVAC, VARODRY, SCREWLINE, SOGEVAC, TRIVAC and RUVAC pumps. You can combine multiple systems in order to obtain the perfect pumping speeds and optimize your cost of ownership.

High vacuum pumping

In the next step of the process, the process chamber is pumped down to a vacuum level of 5x10-6 mbar and lower, a level which needs to be maintained continuously with gas loads of argon, nitrogen and oxygen in operation pressure ranges. Some processes require an oil, dust and vibration-free process environment. In this case, we recommend TURBOVAC i, TURBOVAC MAG or COOLVAC pumps. For less demanding processes, diffusion pumps (DIJ and DIP) are more suitable.
High vacuum systems need the ability to operate continuously with high gas loads for long stretches of time.

Reliable and cost-efficient installations

Leybold pumps are designed for coating applications and have proven their value over many decades. Experience has also taught us that reliability and uptime are key. Therefore, we recommend regular maintenance plans and OEM spare parts. When you take proper care of your vacuum system, you also save on operational costs. Talk to your local Leybold representative to figure out the best solutions for keeping your production up and running at all times.

Process control solutions

Make sure you can always accurately measure the vacuum conditions of your vacuum deposition processes. With our full range of vacuum gauges, you can be sure you always have the ability to monitor the best possible conditions for your processes. Your Leybold representative will be happy to advise you on the best process control solutions. Leak detection and RGA (Redusial Gas Analyzer) systems play an essential role in process repeatability and reliability.

System integration

Our pumps are designed to fit together perfectly, but sometimes your process requires more control and monitoring solutions. In this case, we install PLCs or controllers that support your production processes.
