How does poor quality MRC affect image quality?

Low light transmission and green flaring are common problems with uncoated glass. As MRC coatings are added to each side of the optical disk light transmission steadily increases with flaring steadily decreasing. In our lab tests light transmission apexes at about 16-layers of MRC, and slowly decreasing in transmission at 18 and above. 8-layers of MRC are applied evenly to both sides of each optical disk resulting in MRC16.

Color Neutrality

Worlds Most Color Neutral ND Filter. 100% Guaranteed.

Most of the neutral density filters on the market exhibit a strong blue or magenta cast. The higher the ND factor the more pronounced the color cast. To achieve the most color neutral ND performance we had to develop an alternative manufacturing method to the conventional oven process.

Transmission Curve

Spectrometers are optical instruments that can detect spectral lines and measure their wavelength or intensity. Spectrometers can also be used to test the efficiency of an optical filter in order to determine whether a filter has properly blocked or transmitted specific wavelengths.
A perfectly flat transmission curve would yield a perfectly color neutral result. And while there is no such thing as a perfectly neutral ND filter (cont
