Varia Lenses

Nytea Diagram This line is designed in support of cooled LWIR systems. These high performance long wave focal planes do not require the fast F# as do the uncooled type. This makes the Varia line an economical choice, while still maximizing the camera performance. This similar mechanical features as the Asio line, which allows for the use of the bayonet mount and the same accessories.
