Control the intensity of light without absorbing energy at specific wavelengths!
The "Neutral Density Filter" is a filter with a flat spectral transmittance in the visible range. It is suitable for controlling the intensity of light without selectively absorbing the energy of specific wavelengths, making it ideal for adjusting exposure during color photography and for regulating light levels in various measurement instruments. Due to variations in spectral characteristics depending on the melting conditions, care is taken to maintain the specified performance by adjusting the thickness. Therefore, by differentiating the types of products and adjusting the thickness, it is possible to create combinations of filters with any average transmittance. 【Features】 ■ Flat spectral transmittance in the visible range ■ Controls light intensity without absorbing energy at specific wavelengths ■ Used for exposure adjustment in color photography and light level regulation in various measurement instruments ■ Maintains specified performance by adjusting thickness ■ Capable of creating combinations of filters with any average transmittance *For more details, please refer to the PDF document or feel free to contact us.
