Optometric optical coating system refers to applying single layer or multiple layers of optical thin film of certain thickness on the surface of lens by using physical and chemical processes [...]
The electrode of a crystal is critical for thickness monitoring and rate control. Currently, three standards materials for electrodes are available on the market: gold, silver and alloy. Gold is [...]
If improperly used, the advantages of Quartz Monitor Crystals, even high-quality Quartz Monitor Crystals, cannot be fully utilized. How to properly and effectively use crystals becomes the focus to ensure [...]
Standard Optical Coating Standard optical coating typically consists of 8 or more layers, including ophthalmic lens, camera lens and basic anti-reflection display coatings. Gold crystals are commonly used in these [...]
Metal Vacuum Coating Technology The process in which metal, alloy or compound is evaporated or sputtered in a vacuum and is allowed to condense and deposit on the object to [...]
Piezoelectric Effect of Quartz Crystal and Its Application In 1880, Pierre Curie and his older brother Paul-Jacques Curie discovered the piezoelectric effect of quartz crystal. After breakout of World War [...]
Vacuum Evaporation for OLED: The source material is evaporated into atoms or molecules in a vacuum by heating with electric current, electron beam bombardment or laser etc. Then they move [...]
Background of development of quartz monitor crystals: Quartz crystal components can date back to 1880’s, but have been widely used only in recent decades. The development of the industry [...]
