Nyctea Lenses
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 features of this lens are similar to the Asio line, which allow for the bayonet mount and the use of other accessories.
