A compact, high performance zoom lens for aircraft head-up displays
Case Study 3
We suggested a modified version of our miniature zoom lens. The core of the miniature zoom lens fitted into a special robust body that enabled the zoom and focus movements to be locked so that they did not move even when subjected to aircraft vibration. The new lens can be zoomed to a desired focal length, focused and locked up with only the iris motorised during flight. This approach saved many hours of development time thay would have been needed to design a new lens for this application.
This lens is currently used by several airforces around the world.
