UV filter HT HUC MC

The NiSi UV filter, like all other products, is made of high quality optical glass. For all sizes, we offer exclusive HT (or HUC, High-Ultra-Clarity) glass with very high transparency, the best on the market, exclusive to NiSi. Absorption of UV light, which can cause a blue cast in photos and videos during the day, is ensured by a special absorption treatment that quickly reduces UV light by almost 100% at wavelengths below 365 nanometers.

The HUC high light transmission glass has a visible light transmission of 99.2%, while the frame is milled from a single block.

NiSi UV HT filters (or HUC filters) are manufactured using the most advanced technologies available. The quality control and tests performed allow for incredible precision. Below you will learn how NiSi HUC UV HT filters are constructed: Quality First.
