Ninox Lenses

With an eye to the future, Janos has created a line of multispectral imaging lenses. Infrared imaging companies have been researching focal planes with multispectral sensitivity that range from the mid infrared through the long wave region. By using a lens from the Ninov line, you will have superior imaging over the full multispectral range from 3.0µm though the LWIR. All other features of this lens are like the Asio line, which allows for the bayonet mount and the use of other accessories.
