Abstract

The invention discloses a sapphire camera lens, comprising a lens substrate, a trititanium pentoxide film I, a silicon dioxide film I, an ink layer, a trititanium pentoxide film II, a silicon dioxide film II and an AF (anti-fingerprint) film, wherein the upper surface of the lens substrate is coated with the trititanium pentoxide film I; the trititanium pentoxide film I is coated with the silicon dioxide film I; the silicon dioxide film I is coated with the AF film; the lower surface of the lens substrate is coated with the ink layer; the ink layer is coated with the trititanium pentoxide film II; the trititanium pentoxide film II is coated with the silicon dioxide film II. According to the sapphire camera lens, since the lens substrate is coated with the silicon dioxide films and the trititanium pentoxide films, the light transmission of the sapphire camera lens is increased, the imaging effect of the camera is very clear, and the night imaging capability is improved; moreover, the surface layer of the lens is coated with the AF film, so that the anti-pollution capability of lens glass is increased, the lens glass keeps blue-green for a long time, and in addition, the wear resistance of the lens glass is further improved.

Description

technical field [0001] The invention relates to a camera lens, in particular to a sapphire camera lens. Background technique [0002] In recent years, the technological development of mobile phone cameras is changing with each passing day, and the pixels of the cameras are getting higher and higher. Customers require their imaging quality and imaging environment to be more and more cruel, which requires the clarity and transmittance of the lenses on it to be corresponding. Improvement; In order to achieve the above effects, vacuum coating technology is often used to coat different coatings on the lens to meet the requirements of high definition, while taking into account the effects of wear resistance and high transmittance. However, the current vacuum coating process often has the phenomenon of uneven coating, which leads to the influence of its transmittance and wear resistance. Contents of the invention [0003] In order to solve the above problems, the present inven...
