B Type Linear Fresnel Lens

Flat cylindrical lenses that were developed to efficiently condense sunlight into a slit.　Light is condensed into a straight line, making these ideal for use as an optical module for the collection of heat in linear array CPV modules, pipes, etc.

Contrary to our standard linear Fresnel lenses, this optical module is designed for the light entering from the plano side to be gathered on the Fresnel side.
