Shortpass Filter

A shortpass filter is a type of optical filter that transmits light with wavelengths shorter than a certain cut-off wavelength, and blocks or reflects light with longer wavelengths. It is also known as a low-pass filter or an edge filter.

  • Cutoff Wavelength (Cutoff)

    The cutoff wavelength for a shortpass filter is the wavelength at which the filter's transmission drops to 50% of its peak value.

    In simpler terms, it's the point where the filter starts to block longer wavelengths while allowing shorter wavelengths to pass through.

  • Optical Density(OD)

    Optical Density (OD) is a measure of how much light is absorbed by a material. It's a logarithmic scale, meaning that each increase of 1 in OD corresponds to a 10-fold decrease in light transmission.

    • OD1 - 10%
    • OD2 - 1%
    • OD3 - 0.01%
    • OD4 - 0.01%
    • OD5 - 0.001%
    • OD6 - 0.0001%
