Neutral density filter, referred to as nd mirror (attenuator), is used to filter light. This filtering effect is non selective, that is, the reduction ability of Nd mirror to light of different wavelengths is the same and uniform, only plays the role of reducing light, and will not have any impact on the color of the original object, so it can truly reproduce the contrast of the scene; There are two kinds of attenuators: the first is reflective neutral attenuator and the second is absorption neutral attenuator.
The Main Characteristic Parameters Of The Attenuator Are:
① : Working Wavelength Range;
② : Attenuation Ratio (transmittance);
③ : Nd Value Or Od Value;
④ : Reflective Attenuation;
⑤ : Absorption Attenuation.
Application Area
Strong Light Weakening, Laser Equipment, Detection Equipment, Impact Equipment, Optical Communication Transmission, Etc; After Light Passes Through The Attenuator, Different Wavelengths Are Attenuated In The Same Proportion.
