Description

Technical Field

[0001] The utility model relates to the technical field of optical lens coating, in particular to a vacuum coating machine for optical lens coating. Background Art

[0002] Optical glass is a mixture of high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, and barium, mixed according to a specific formula. It is melted in a platinum crucible at high temperature and stirred using ultrasonic waves to remove air bubbles. The glass is then slowly cooled over a long period of time to prevent internal stress. After cooling, the glass is tested with optical instruments to verify its purity, transparency, uniformity, refractive index, and dispersion. Qualified glass blocks are then heated and forged to form optical lens blanks.

[0003] Lens coating refers to applying a special thin film on the surface of optical devices such as glasses or camera lenses to change their optical properties and performance.

Therefore, those skilled in the art provide a vacuum coating machine for optical lens coating to solve the problems raised in the above background technology. Utility Model Content
