Embodiment 1

[0037] The moisture-proof and mildew-proof optical film involved in the present invention is realized on a Leybold SYRUSpro1110 vacuum coating machine; the equipment is equipped with an APSII plasma source, an electron beam evaporation system, and an IC5 film thickness monitor.

[0038] refer to Figure 1 to Figure 3 As shown, the present invention discloses a moisture-proof and mildew-proof optical film with high transmittance, including a substrate 1, a high-density anti-reflection film system main body 2 and a hard wear-resistant protective layer 3 evaporated on the substrate 1 in sequence , the first hydrophobic film layer 4 and the second hydrophobic film layer 5; the substrate 1 is glass, sapphire, zinc sulfide or silicon wafer of the same material as the optical window, so the substrate 1 of the present invention can be Lay on the optical window and form an integral body with it, and the optical window can also be used as the substrate 1 to evaporate other film layers seq...

Embodiment 2

[0044] A high-efficiency anti-reflection film with moisture-proof and mildew-proof functions coated on a K9 glass light window, the size . The technical requirements are as follows: , incident angle 0-30 0 . The coating sample passed the high and low temperature, constant humidity, adhesion and severe friction tests specified in GJB2485-1995 at one time. At the same time, it can also withstand the mold test specified in GJB150.10A-2009.

[0045] First of all, according to the above technical requirements, the optimal design of the film structure is carried out, and the results are as follows:

[0046]

[0047] Among them, the material of the hard wear-resistant protective layer 3 is selected as SiO 2 , a-f are the physical thickness of the film layer, respectively, M1 and M2 are both fluorine-silicon-based organic hydrophobic film layers, and their physical thickness is 6.0nm. The physical thickness of other film layers is as follows:

[0048] a-70.25nm; b-82.66nm;...

Abstract

The invention discloses a moisture-proof and mildew-proof optical film, which comprises a substrate, a high-density anti-reflection film system body, a hard wear-resistant protective layer, a first hydrophobic film layer and The second hydrophobic film layer; its preparation process is also disclosed; the typical characteristics of the present invention are high optical window transmittance after coating, smooth surface and wear resistance, good moisture-proof and mildew-proof performance, and the preparation process is easy to transplant. The invention can effectively solve the moisture-proof and mildew-proof problems in the actual application of the optical lens, and can be widely used in military and civilian optoelectronic technical fields such as military optoelectronic equipment, precision optical instruments, and outdoor monitoring cameras in high-humidity environments.

Description

technical field [0001] The invention belongs to the technical field of optical films, and in particular relates to a moisture-proof and mildew-proof optical film with high transmittance applied to protective windows such as glass and optical crystals, and a preparation method thereof. Background technique [0002] In a variety of harsh environmental conditions, the growth of mold and the erosion of moisture are one of the important factors that cause the protection window of optoelectronic equipment to be corroded and damaged. In fact, mildew on the surface of the optical window is essentially the result of destructive chemical corrosion. Once dense mildew spots are formed, they cannot be removed. Over time, it will directly affect the optical performance of the system and the service life of the optical window. [0003] Studies have shown that molds will continue to secrete corrosive toxins during the growth of glass or optical crystals. However, conventional AR coatings c...
