Diffraction Limited Aspheric Optics

Optical Surfaces has supplied the key focusing optics for a new low-cost Fibre Lidar system recently launched by QinetiQ for making local wind speed measurements in front of wind turbines. The company has been a pioneer in the development and implementation of Lidar systems for wind sensing for over 20 years. Their Fibre Lidar Anemometer provides remote wind speed and direction measurements up to 200 m distant. Apart from many meteorological and Air Traffic Control applications the lidar offers a unique advantage to the wind energy industry providing warning of turbulence and wind speed changes that will permit intelligent blade pitch control.
