Advantages of multilayer coated lens

The coating on the photographic lens has the advantages of reducing light reflection and improving light transmittance. Coating is mainly to reduce reflection. In order to improve the transmittance and imaging quality of the lens, it is necessary to coat the lens in modern lens manufacturing technology. According to the principle of optical interference, a layer of substance (usually fluoride) with a thickness of quarter wavelength is coated on the lens to minimize the reflection of colored light at this wavelength.

Camera:

A camera is a device that records images by using optical principles. The invention of the camera was originally used for the production of movies and TV programs, but now it has become popular. Just like cameras, early cameras needed to use negatives (that is, video tapes) for recording, but now the invention of digital cameras enables images to be stored directly in flash memory. Newer cameras directly store image data in the hard disk of the fuselage, which can not only record dynamically, but also shoot statically, without bringing a digital camera at the same time.
