Specifications

  • Cuton Wavelength (Cuton)

    The cut-on wavelength for a longpass filter is the wavelength at which the filter's transmission increases to 50% of its peak value.

    • Wavelengths below the cut-on wavelength are typically blocked.
    • Wavelengths above the cut-on wavelength are typically transmitted.
    • The steeper the transition from blocking to transmission (often referred to as "edge steepness"), the better the filter's performance.

  • 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%
