Precautions For Use Of Optical Filter
Precautions For Use Of Optical Filter
The filter is used to attenuate (absorb) some light bands in the light wave or select a small range of light waves to pass through while reflecting (or absorbing) other unwanted bands. By changing the structure of the filter and the optical parameters of the film, various spectral characteristics can be obtained, so that the filter can control, adjust and change the transmission, reflection, polarization or phase state of light waves.
Precautions for use of optical filter
1. During normal use, it shall be taken and placed as carefully as possible, and pay attention to the external environment to avoid scratching the filter by the zipper and button of clothes, or placing the filter in a dirty or dusty environment.
2. Wear a finger sleeve when contacting the filter to avoid the corrosion of the substrate surface by salt and acidic substances on your hands.
3. When taking the filter, hold the edge of the filter by hand, and do not touch the light transmission surface of the filter even with a finger sleeve.
4. The filter should be placed on a soft and clean object, not on glass, metal, table or unclean paper.
5. Store in clean capacitor paper or lens cleaning paper. The storage temperature is about 23 ℃ and the humidity is not higher than 40%. It's better to put it in a dry storage cabinet.
6. Do not stack the filters together to avoid wear.
7. If there are stains or finger marks on the surface, wipe it with absolute ethanol or similar functional solvent.
