How did the bandpass filter scratch?

Definition and description of the scratches or scratches of the filter: the briquette or strip-shaped scars of the filter surface and other harder substances are scratched or scratched, mainly as scratches. Or the light transmittance of the filter is increased, or the filter membrane faces light is translucent. Scratched parts are mostly irregular curved strips or strip shapes.

The main causes of scratches or abrasions have the following points:

1. filter production: due to equipment or post-cleaning, in the production of filter production in filter production, this scratch is generally rule and linear type, which is controlled And tested. In addition, the handling of the filter coated glass during the production process is also likely to be scratched, and the original sheet itself may also be scratched.

2. filter cutting causes: for example, the drag of the filter surface of the filter is cut; the film surface caused by the filter wiping during the filter surface of the filter surface; The plating surface is cut down or not noticed that the last piece of each box is a reasons such as reverse direction, causing the filter membrane surface to be scratched with other friction.

3. filter stacking and storage: After the filter is out of the box, the filter is not stacked as required, and there is no liner between the sheets, causing direct contact between the filter, in handling It is caused by scratches or filters during transportation.

4. filter mounting and cleaning: filter(222nm bandpass filter pass 222nm block visible light) caused by hard objects due to hardware; in the filter cleaning, or filtering The light sheet surface has contaminants, and incorrect cleaning methods are used.
