    Neutral Density Filters

    Also known as Neutral Density (ND) Filters or Optical Attenuators.

    Functions:
    Uniformly attenuates light intensity across visible and near-infrared (NIR) spectrums via absorption or reflection, effectively controlling exposure and light transmission without altering spectral color balance.

    Applications:
    Laser power control and beam attenuation
    Automated optical inspection (AOI) systems
    Optical instruments and measuring systems
    Imaging and camera exposure systems

    Information and Notes

    1. Neutral Density (ND) filters can be customized to customer specifications or tailored for precise target transmittance at specific wavelengths (e.g., 532 nm, 635 nm, 850 nm, 940 nm).

    2. ND filters feature metallic thin films deposited via vacuum evaporation. Due to their partial absorption and partial reflection characteristics, the sum of total transmittance and total reflectance will be less than 100%.

    3. Coating process: PVD-EBGE (Physical Vapor Deposition - Electron Beam Gun Evaporation).

    4. The spectral transmittance curves shown are measured at a 0° angle of incidence (AOI = 0°). Transmittance values represent the average across the visible spectrum.

    5. Spectral curves represent actual sample measurements and may vary slightly from manufacturing lot to lot, while remaining within defined optical specifications.

    6. Website specifications are for reference only; final shipments are subject to the agreed specifications confirmed by both parties.
