Optical Surfaces Ltd. has received a sizeable repeat order to produce optical modules for the ZephIR® 300 wind lidar from Natural Power.

A spokeperson at Optical Surfaces Ltd commented ‘Renewable energy is an important part of the future – we were delighted to receive the repeat order for the ZephIR 300 optical modules from Natural Power. To achieve the ultimate in performance with the fewest components our optical module incorporates a 200mm focal length aspheric doublet. The ability of the ZephIR to produce variable focus at different heights is achieved by using a “point” source originating from a single mode fibre which is located at different longitudinal positions just beyond the front focal plane of the optical module. The aspheric lenses in the optical module have a durable V-coat to allow the lens surfaces to be cleaned and to optimise performance at 1.5 μm’.

The accurate prediction of energy yields is fundamental to the success of wind farm projects. The ZephIR 300 wind lidar (www.naturalpower.com/zephir-300-wind-lidar) provides complete wind resource measurement including horizontal and vertical wind speed, wind direction and turbulence at any height up to 200 metres without the need for a mast thereby eliminating the need for planning permission or working at height. The portability of ZephIR and ease of deployment makes high density data collection a reality with 50 measurements per height per second, both horizontally and vertically across the extent of the measurement site.

Optical Surfaces Ltd. has been producing optical components and systems for more than 45 years and is now accepted as one of Europe’s leading manufacturers of high-precision optics for remote sensing and environmental research. The company’s ISO 9001-2000 approved manufacturing facility provides the flexible resources to supply from single specialist requirements to OEM quantities. All high precision optics are provided with a complete quality test assurance report.

Natural Power collaborates with educational institutes and R&D houses, and invests in new technologies that add value to renewable energy projects. Through a team of in-house specialists including project managers, ecologists, GIS and mapping experts, construction managers, wind farm designers, geotechnical engineers and land agents – Natural Power have developed a portfolio of advanced natural power tools which provide great benefit to clients.
