Neutral density filters

Neutral Density Filters for Control of Light Intensity

Neutral density (ND) filters reduce light intensity in the visible region of 400 to 700 wavelength range.

Neutral density glass characteristics may vary with melting conditions but the filter performance can be compensated by changing the filter glass thickness.

Neutral density filter applications:

  • Exposure control in color photography
  • Calibration filters
  • Light control in various instruments
