ZhuHai CUFU Optical Technology is integrated in the R&D and manufacture of a variety of filters under the brand “NISI”. In 2007, NISI ultra thin filter was launched to the market; its ultimate performance got unanimous recognition among optical experts. In 2009, we have developed LR UV filters with golden ring which caused a shock in the filter industry.

NISI filter glasses come from AGC in Japan and Schott in Germany--world-class high-quality optical glass suppliers. With double side, anti-reflection, multi-coating, water-, stain- and scratch-resistant, and high level of parallelism on the surface, NISI filter can assure top level of transmittance and ultra low reflectivity.

NISI series use high-quality aviation aluminum, its frame is only 5.2mm, the thinnest in the world so far. NISI filter's frame surface is with fine sand blasting and anodic oxidation, while dull finish inside for anti-reflection. With fine knurling on its rim, the frame makes the lens exceptionally easy and comfortable to rotate. Automatic-locked ring clamping makes the lens safe from damage during transportation.
