NiSi IR ND uses H-K9L high quality optical glass, with double-sided nano-coating, to reduce the intensity of visible light entering the lens, It will not change the brightness contrast of the scene, and also provides effective inhibition of ultraviolet and infrared light. The Nano Coating technology of NiSi IR ND has been innovated by NiSi Filters. Please visit NiSi IRND page to get more tech information.

- Core Bundle (Three pieces): 0.3/0.6/1.2. You can also choose any three pieces of glass including different f-stops even polarizer, the same size;
- Professional Bundle (Six pieces): 0.3/0.6/0.9/1.2/1.5/1.8. You can also choose any six pieces of glass including different f-stops even polarizer, the same size.
