Embodiment 1 As shown in FIGS. 1-6, the filter unit laser skip cutting method in this embodiment is used for cutting a filter original sheet 1 into a plurality of filter units 2.

The filter element 1 refers to a filter that has not been cut, and after the filter element 1 is cut into a plurality of filter units 2, the size of each filter unit 2 may be close to the size of the product to be finally applied. For example, assuming that the filter element 1 is finally mounted in the camera after the subsequent processing, the dimensions of each filter unit 2 formed by cutting the filter element 1 are substantially the same as those of the filter element when finally mounted in the camera.
In practical applications, the materials specifically included in the inorganic optical composite layer 11, the organic dye layer 12 and the substrate layer 13 included in the filter element 1 may be selected according to the final product of the filter unit 2, which is not limited herein. In practical applications, the substrate layer 13 may be an organic substrate, an inorganic substrate, or a multi-layer composite substrate (e.g., including a plurality of organic layers and a plurality of inorganic layers). The substrate layer 13 serves as the primary support structure for the filter unit. The organic dye layer 12 is used to absorb light beams of a specific wavelength range so that it cannot pass through the filter unit 2. The inorganic optical composite layer 11 is used to determine which specific wavelength range of light beams is allowed to pass through the filter unit 2.
For example, in the case that the filter unit 2 is finally applied to a camera lens, glasses, front windshield of an automobile, etc. for filtering invisible light and passing visible light, the substrate layer 13 may be an inorganic substrate such as blue glass, white glass, etc., the organic dye layer 12 may be a dye (ultraviolet light absorber, infrared light absorber), an adhesive, a leveling agent, etc. that absorbs light of a specific invisible light, the inorganic optical composite layer 11 and the secondary inorganic optical composite layer 14 may be a stack of a plurality of first refractive layers H and a plurality of second refractive layers L that are stacked alternately, and the refractive index of any one of the first refractive layers is higher than the refractive index of any one of the second refractive layers, i.e., hlhl. Regarding the design of the total number of the first refractive layers, the thickness of each first refractive layer, the total number of the second refractive layers, the thickness of each second refractive layer, and the like included in the inorganic optical composite layer 11, the refractive index, the transparent region, and the thickness of the organic dye layer 12 should be considered together, and the entire organic dye layer 12 is considered as a third refractive layer n in consideration of the spectral design. The design of the final film layer is nhhl. And is designed according to the situation of the practical filtering unit and the wavelength range of the light beam to be filtered. The specific materials of the first refractive layer and the second refractive layer are not particularly limited as long as they meet the desired optical characteristics (for example, refractive index, extinction coefficient). For example, the first refractive layer and the second refractive layer may each include an oxide, a nitride, an oxynitride, a carbide, other suitable optical coating materials, or a combination thereof, and specifically may include, but not limited to, silicon hydride, silicon oxynitride, silicon dioxide, aluminum oxide, titanium dioxide, niobium pentoxide, tantalum pentoxide, silicon nitride, silicon oxynitride, silicon carbide, magnesium fluoride, zirconium dioxide, and the like.
