The filter has a hard coating that protects the lens and sensors by preventing UV light from entering the camera. It blocks out blue light which prevents images from looking bluish or whitish when shooting in open spaces like at sea or in large fields. High transmittance, doesn't affect image sharpness.
The ND filter also called the Reducing Light filter, or Neutral Density filter reduces the amount of light in very bright conditions so that the camera can choose the correct exposure value and avoid excessive exposure.
CNC aluminium frame makes the filter extremely light,
yet robust. It is corrosion proof and carefully engineered to
not affect your drone's balance.
The filter uses German SCHOTT glass as its base material, which has been ground and polished multiple times to create a low refractive index for color accurate photo capture.
The filter's double-sided, multi-layered coating repels water and oil, which makes it easy to keep clean. The filter's hard coating also makes it scratch resistant.
The filter's optical glass contains a refection reducing coating to maintain color accuracy and balance.
