The NiSi Explorer Collection is made for adventure. The filters feature a special glass hardening process that makes them double the strength of a typical glass filter. The Explorer series are much less prone to accidental breakage and perfect for active photographers. The NiSi Explorer Collection filters are made from B270 tempered glass. It features the same Nano coating process as our optical glass filters.

High Definition

NiSi always brought to life incredible High Definition filters thanks to its Lens Grade Optical Glass.
The grade of optical glass used by NiSi cannot be found in any other filter by any other manufacturer. The only other place you will find glass of this standard is in high-end optical lenses such as the best macro lenses; Nikon™ gold series, Canon™ L lenses, Zeiss™ lenses, Sony™ GM and a few other specialist applications that require the utmost in optical precision.

NiSi Explorer Filters

The NiSi Explorer Collection is made from B270 tempered glass, with a lower transmittance compared to our main filters lineup with Lens Grade Optical Glass, but with the peace of mind of having Hardened Tempered glass able to resist accidental damage when falling*.

If you don’t want any compromise in transmittance, discover our NiSi Optical Glass ND and GND range. If price matters most, you’ll find the quality of NiSi Coatings on B270 Glass (same standard as competitors) at a better price in our Explorer range.

NiSi Nano-Coating®

NiSi Nano-Coating is a treatment for optical glass that makes it water and oil repellent. Thanks to this coating we deliver a number of advantages, including much easier cleaning of rain, spray and handprints. This allows for maximum sharpness in every situation.

Why NiSi?
NiSi Nano-Coating repels water and oil, making cleaning much easier.

IR treatment

The anti infrared light treatment (or simply “IR“) blocks infrared light beyond a certain wavelength. IR pollution is responsible for the dominant magenta colour cast introduced, or more accurately, allowed through, by low-quality filters. The light absorption curve in NiSi filters is extremely uniform, ensuring a very high colour match.

Why NiSi?

In these graphs, we observe how the response of the NiSi ND (Neutral Density) filter (top left) is uniform, virtually perfect, at all wavelengths; both visible and invisible. It is important to know that even if the eye does not see certain wavelengths, the camera sensor captures them and the colours are altered. All other filters tested (each one of them popular, high priced brands) have a less flat, irregular curve, especially in the final part, infrared.

Essentially, an uneven line in transmission charts demonstrates that the filtration is uneven across the spectrum; the filter is letting in more or less light in certain wavelengths by comparison to others.

Neutral Density filters are so named because they are required to be neutral; to not give bias to any wavelength over another. So if your filter has a tendency to allow excess UV (blue/cooler) or IR (red/warmer) through, you don’t have a Neutral Density filter.
