Neutral Density Filter

This glass filter is designed to provide an even spectral transmission over the visible spectrum. We can also modify desired densities.

Applications: for adjusting the amount of light entering a camera



ING125 (1.3MB) ING375 (1.3MB)
ING250 (1.3MB) ING460 (1.3MB)



Used to uniformly reduce the amount of light in visible regions. Used as a filter to adjust the amount of light entering a camera.


1)Tempering can be customized depending on your application.
(To improve heat resistance or high impact resistance)
Note: After the tempering process spectral characteristics may slightly shift from original one.
2)Spectral characteristics shown on this website are nominal values. The transmission curves can be calculated for a given thickness and are for reference purpose only.
3)Spectral characteristics shown here are measured at room temperature (25degrees C, 50% relative humidity)
4)Please consult us about applications and ambient condition.
