Filter

  • Absorptive Filters: absorb specific wavelengths of light while transmitting others
  • Reflective Filters: reflect the undesired wavelengths while transmitting the remaining ones
  • Monochromatic Filters allow a limited range of wavelength to pass
  • Neutral Density (ND) Filters are utilized to reduce the intensity of light by reflecting or absorbing a percent of light at specific wavelengths
