[0021] In the description of the utility model, if the meaning of several is one or more, the meaning of multiple is two or more, greater than, less than, more than, etc. Understand as not including the number, above, below, within, etc. Understand as including the number. If it is described to the first, the second is only used for distinguishing the purpose of technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the relationship between the indicated technical features.

[0022] Referring to Figures 1 to 11 The utility model discloses a photography filter assembly, it includes: first optical glass 11 and second optical glass 12, first optical glass 11 has the basic filter 20 of cementation on, second optical glass 12 has the soft light glue layer 30 of coating, and soft light glue layer 30 evenly distributes with softening particle, and soft light glue layer 30 is bonded with basic filter 20. Put the basic filter 20 and soft light coating in the middle of two optical glasses, use a basic filter 20 to satisfy the extinction and softening effect of two kinds of filters (basic filter 20+ soft light mirror) simultaneously, combine the shooting effect of basic filter 20 and soft light mirror, reduce the work of photographer dismounting filter, convenient to use and carry, obviously reduce the filter number, not only reduce the multiple halos of originally multiple filters, make the image quality more clear and transparent, but also make the overall thickness of filter assembly reduce, increase the field angle indirectly, reduce the appearance of shooting dark corner, and, multiple lenses become single component, reduce the production cost.

[0023] As Figure 2 The filter assembly also includes an antireflection film 40 and a waterproof film 50, the antireflection film 40 is arranged on the outer surface of the first optical glass 11 and the outer surface of the second optical glass 12, and the waterproof film 50 is arranged on the antireflection film 40, so as to achieve the effects of antireflection and waterproof.

[0024] The basic filter 20 includes a CPL filter, a VND filter or an ND filter, for the CPL filter assembly, first, the optical glass is processed, and the surface of the optical glass is polished; then the CPL polarizer is cemented on the first optical glass 11; the soft light glue layer 30 is coated on the surface of the second optical glass 12; then the two optical glasses are bonded, the surface of the CPL polarizer and the soft light glue layer 30 are bonded with each other; then the glue layer is degassed, and then the glue layer is solidified; finally, vacuum coating is carried out. That is, the CPL polarizer and the soft light coating are both put in the middle of the two optical glasses, and one filter can satisfy the extinction and softening effect of two kinds of filters simultaneously.

[0025] For the VND filter assembly, the VND filter comprises two CPL lenses, one CPL polarizer is glued on the first optical glass 11; a soft light glue layer 30 is coated on the surface of the second optical glass 12; then the two optical glasses are pasted, and the surface of the other CPL polarizer and the soft light glue layer 30 are pasted with each other. That is, one of the CPL lenses is pasted with the soft light glue layer 30 to form a soft light VND, which retains the adjustable gear function of the traditional VND while making the photographed photos have a softening effect, meeting the vast majority of shooting scenes.

[0026] The structure and process can also be extended to other types of filters. For example, an ND soft light filter can be made by adding a soft light glue layer 30 between the ND filter and the optical glass; a starry night soft light filter can be made by adding a soft light glue layer 30 to the starry night filter, and so on. Different types of soft light filters can be made according to needs to meet various use scenarios.

[0027] Preferably, the soft light glue layer 30 refers to mixing soft light particles with a diameter of φ0.01-φ0.05mm in photosensitive glue. The soft light particles include but are not limited to carbon powder particles (main component is carbon), quartz particles (main component SiO2), and other particles (such as PMMA, polypropylene, and other high molecular materials). The particles are uniformly distributed in the coating, and different specifications of soft light effects are produced by using different particle diameters, corresponding to different specifications and gears of soft light filters. When the particle material is black particles such as carbon powder, a black soft filter can be made; when the particle material is white particles such as quartz or high molecular materials, a white soft filter can be made; other colors of soft light materials can also be selected according to actual needs to make soft light filters of different colors and specifications.
