中性密度滤光片

ND Filters are used to reduce transmission evenly over a range of wavelengths in a variety of applications including microscopy, imaging, or spectroscopy. ND Filters reduce the intensity of light by absorbing or reflecting an even portion of the transmitted light determined by the filter's optical density. ND Filters are available in a wide range of densities or materials that may be stacked together to increase optical density.


中性密度吸收滤光片
  • 通过吸收(而非反射)减弱可见光
  • 可堆叠多个滤光片以提升拦截效果
