How did the bandpass filter film layer fall off?

The filter film layer is defined and explained: the local film layer exhibited by the surface of the coating filter layer or the release. The filter is mainly manifested as a partial light transmittance reinforced or the filter film layer is completely detached, and the delay form is generally pointing, reunite and sheet shape. The filter membrane layer falls off and produced during the production process, and we have strict standard control.

The filter causes a large cause of the membrane layer, and the main reasons have a few aspects:

Summary of filter production: Due to the filter coating process, some needle membrane layers may appear in the production of filter production. Because the filter coating original or equipment cleaning is also possible, it is possible to cause the membrane layer to fall off, and the national standard has corresponding requirements and regulations. Our factory products are strictly inspected, and the filter is qualified.

The filter transport membrane is detached: after the filter is handled or after cutting, it is not unconfilled between the filter and the filter, causing the filter directly to contact, and the film surface is directly The relative friction causes the membrane layer to fall off.

The filter(customizable transparent 222nm filter coated UV filter) corrosive membrane layer is detached: the incorrect method is used due to the filter surface of the filter film, or the cleaning, the filter film surface is used to contact the oxidizing substance, resulting in the filter surface of the filter. Pollution corrosion and the membrane layer falls off.
