Nyctea Lenses

Nytea Diagram

Many MWIR imagers have sensitivity down below 3µm, into the near IR. By using a lens from the Nyctea line, you will expand your ranges from the laser line at 1.5µm through the mid infrared. All other feature of this lens are similar to the Asio line, which allow for the bayonet mount and the use of other accessories.
