  • Center Wavelength (CWL)

    The wavelength mid-point of transmission range.It is usually measured in nanometers (nm) and it indicates the color of the light that passes through the filter.

    • Typical CWL in UV Range: 250 - 390nm
    • Typical CWL in VIS Range: 410-700nm
    • Typical CWL in NIR Range: 800 - 1550nm
  • Transmission (Tmax or Tmin)

    The maximum (or minimum) transmission value within the transmission band. It depends on the coating quality, substrate material, and angle of incidence.

  • Blocking Region

    The blocking region for a bandpass filter is the range of wavelengths that the filter blocks or attenuates.It is the opposite of the passband, which is the range of wavelengths that the filter transmits.

  • FWHM

    FWHM stands for full width at half maximum, which is a measure of how wide the transmission band of a filter is. For example, a FWHM of 10 nm means that the filter transmits wavelengths within 5 nm on both sides of its center wavelength at half of its peak transmission value

  • Optical density (OD)

    The measure of how much light is blocked by the filter outside the transmission band. It is expressed as a logarithmic ratio of incident and transmitted power. A higher optical density means a deeper blocking.

    Notes:

    • Soft Coating can reach OD2-OD4
    • Hard Coating can reach OD4-OD6
    • Stacking Multiple OD6 Can reach OD8 or Higher
  • Angle of Incidence (AOI)

    Bandpass Filters are very sensitive to Angle of Incidence, usually the AOI is 0 deg. for bandpass filter. Using different AOI may result in very different spectral performance.

couldnt find info on proper filter orientation

I couldnt find info on proper filter orientation. There are arrows on the filters, but Ive seen different conventions on what these mean. This should be in "Tutorial" section, Id think. Please contact me with proper orientation rules. (Although Im still not sure exactly why this matters...)

Hi, reply by cynthia from SO:
For best performance, the coated side of the filter should face the heat source (light). This minimizes the potential for heat damage that can occur when the filter absorbs strong light.
