NiSi is a leading researcher and developer of optical glass manufacturing techniques operating since 2005, with the major production factories based in China. NiSi manufactures optical filters, neutral density filters, filter holders, lenses, and other still and video camera accessories with more than 500 products in our range. Innovation continues with NiSi creating 10 – 20 new products per year to suit a range of cameras.

We pride ourselves on producing the highest quality optical products to allow photographers to produce the best quality images with optimal clarity, sharpness, and color reproduction.

NiSi manufacture lens filters with the highest grade optical glass. Our glass is manufactured and produced directly within our own factories – meaning we can control the quality from start to finish. This standard of glass is typically only found on the highest quality precision optical lenses such as high-end medical imaging equipment, telescopes, and in high-end lenses by manufacturers like Canon, Sony & Zeiss.
