Solar power is set to play a significant role in the energy of the future. Currently, solar panels are proving most prevalent in practicality for domestic applications, and commercial schemes are following suit with larger-scale PVs. Solar farms are also rising in popularity as more people open up to the profitability of income per acre. Fresnel lenses are an excellent component for photovoltaic applications. Due to their thin formation, they lose little light and allow for maximum collection and collimation. Recently, we have seen a spike in interest for our Fresnel lenses for photovoltaic applications due to the customised options offered. From dome-shaped to lenses with a curvature, we can tailor components to your precise requirements.

Wind turbines

Light Detection and Ranging (LiDAR) technology has recently been recognised for increasing efficiencies in wind turbine power. The surveying method measures atmospheric conditions such as the speed and direction of wind and uses light to assess the elements surrounding turbines; allowing optimum energy outputs. Mounted to the wind turbine itself, the LiDAR system automates the adjustment of the turbine’s blades to increase energy generation. At Knight Optical, we supply many components for LiDAR applications including front-coated mirrors, cover windows and optical filters.  Like all our components, optics for LiDAR applications are available tailored to your project’s requirements.
