Background

When light enters the glass from air, about 5% of the light is reflected, and a plurality of lenses and refractors are arranged in optical equipment such as an optical telescope, a magnifying glass, a photographic lens and the like, so that the total loss of the incident light can reach 30-40%. Modern optical lenses usually adopt a coating process to reduce the reflection amount of light, and usually adopt a single-layer or multi-layer fluoride antireflection film, the reflection can be reduced to 1.5% by the single-layer antireflection film, the reflection can be reduced to 0.25% by the multi-layer antireflection film, and the light transmittance is greatly improved by coating.

Generally, the lens is clamped by a clamp in an ionized steam environment, and the film is coated by a thin film deposition method. However, the conventional fixture can only hold a single specification of lens, and the lens on each fixture adopts a single-layer or multi-layer coating process at the same time. The clamp is inconvenient for the simultaneous film coating operation of lenses with various specifications, and also has a lot of inconvenience for the replacement and shelving operation of the lenses.
