Linear Transmittance Filters

A linear transmittance filter (LTF) has a gentle slope in its transmittance characteristics. It is also known as a color balance filter (CBF) and light balancing filter (LBF).

It is widely used in image processing for photography and video production, as well as for correcting the light source in spectroscopes.
Our filter is manufactured with values that are extremely close to the design specifications. You can select any wavelength and transmittance slope according to your requirements.
