기능

• By creating a tiny dot pattern of an aluminum deposited film and changing the area ratio of the dot pattern, a transmittance distribution is created in the filter.
• Use to adjust the amount of light.
• With an AR coat on the back, a high transmittance of 98% can be obtained at maximum transmission.
• Transmittance varies in proportion to the amount of rotation.
• (Transmittance Variable Area) * This ND filter cannot be used for laser light.
• * Use under white or LED light.
• * If a filter is inserted at a position that is confocal with the observed object, the dot pattern of the filter may cause it to project.
• * Be careful when placing the dot pattern on the filter so that the image does not form.
