NiSi Square Nano IRND 100x100mm ND1000K 20Stops

NiSi Square Nano IRND 100x100mm ND1000K – 20 Stops with IR protection for true-to-life colors

The NiSi Square Nano IRND 100x100mm ND1000K 20Stops is a neutral density filter made for photographers who need long exposures while preserving color accuracy. It uses high definition optical glass and a double-sided nano coating. In addition, NiSi added an infrared protection layer to reduce unwanted infrared red cast that can appear when shooting at small apertures.

Key features

• High definition optical glass (not resin), maintaining image detail.
• Double-sided Nano Coating that repels water and oil, helping keep the surface clean.
• Infrared (IR) protection coating that reduces infrared contamination and restores natural color when using long exposures or small apertures.
• Ultra low colour cast and ultra low reflection for faithful color rendering and reduced ghosting.
• No vignetting when used as intended with compatible holders and lenses.
• Available as a 20-stop filter in the square 100 x 100 mm size (ND1000K).
• Manufactured from Environmental Optical Lens glass (H-K9L).

What this filter does and when to use it

Use this ND1000K 20-stop filter when you need to dramatically lengthen exposure time for creative effects, such as smoothing water or showing motion in clouds. It lets you shoot longer exposures without changing aperture or ISO settings. Moreover, the IR protection layer helps capture colors that are truer to what you see in the scene, especially when working at small apertures where infrared contamination can cause a red cast.

Available densities and compatibility

While this product listing refers to the 20-stop ND1000K in the 100 x 100 mm square format, NiSi also offers the Nano IR Neutral Density filters in a range of other stop values for the same 100 x 100 mm size. These include:

FAQ

Question: What material is the NiSi Nano IRND filter made of?
Answer: The filter is made from high definition Environmental Optical Lens glass (H-K9L), not resin, which preserves image detail.

Question: Will this ND filter change the colors in my photos?
Answer: Neutral density filters are designed not to affect coloration. Additionally, this NiSi Nano IRND includes an IR protection coating to reduce infrared-induced red cast and help restore natural colors, especially when shooting at small apertures.

Question: Is the surface easy to keep clean during outdoor shoots?
Answer: Yes. The filter has nano coatings on both sides that repel water and oil, making it easier to wipe clean and maintain during use in the field.

Question: What kinds of photography benefit most from a 20-stop ND filter?
Answer: Long-exposure photography benefits most—landscape photographers commonly use 20-stop ND filters to create effects like silky water or streaked clouds by allowing significantly longer shutter speeds without changing aperture or ISO.
