Neutral density filter（IND series）Optical filters
This glass filter is designed to provide an even spectral transmission over the visible spectrum. We can also modify desired densities.
for adjusting the amount of light entering a camera
Note: To be able to get transmission by thickness values, you must first download the file into your desktop before you can input the desired thickness.
- 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.
