Glossary
  • neutral density filter A light filter that equally decreases the intensity of all wavelengths of light without altering the relative spectral distribution of the energy.
  • light filter A homogeneous optical medium or coating that transmits only in particular regions of the spectrum. It is used to change or modify the total or relative energy distribution of a beam of light.
  • optical density A measure of the transmittance through an optical medium. Optical density equals the log to the base 10 of the reciprocal of the transmittance. where τλ is transmittance. In spectroscopy, optical density is the measure of absorbance, and...
  • optical filter An optical filter is a device that selectively transmits or blocks specific wavelengths, or colors, of light. Optical filters are used to control the spectral content of light in various applications, allowing certain wavelengths to pass through...
