Vacuum Coating Pre-Cleaning: Dedicated Ultrasonic Cleaning Machines – A Head-to-Head Brand Comparison
In vacuum coating processes such as PVD (Physical Vapor Deposition) and CVD (Chemical Vapor Deposition), the quality of the final coating is directly determined by the cleanliness of the substrate. A single speck of oil, a microscopic particle, or a resid
Ultrasonic washing machine for coating pretreatment
On the back of the optical glass, a metal silver (or aluminum) film is coated by a vacuum coating to make the incident light reflect the optical element. The output power of the laser can be doubled by using a reflector with a high reflection ratio, which
