Microsharp thin film Fresnel lenses

Microsharp microstructured thin film Fresnel lenses are an attractive alternative to existing solar lens technologies. Our proprietary conical and curved lenses include a number of elegant design innovations which deliver outstanding performance.

Benefits include...

  • High optical efficiency - typically >85%.
  • A low cost, high speed manufacturing process
  • Precise structure replication
  • Design flexibility - up to 40cm edge length
  • Designed to precise customer specification
  • Low development and tooling cost.
  • Tighter focal spot definition 
  • Shorter focal depth

Linear Fresnel lenses                                     bull

Focus light to a 'strip' and used in Thermal and low concentration PV systems. Can be designed either flat or curved at widths of up to 1m at any desired length  

 
 

  Our Service

Microsharp offers a bespoke lens design and development service to ensure each lens perfectly matches the requirements of a customer's system.

 This service includes...

  • Lens design and performance modelling using proprietary in-house software packages
  • Production tooling design and manufacture
  • Initial hand cast test samples
  • 'Pilot plant', small scale test manufacturing
  • Full scale commercial manufacturing (current internal capacity 1.5 million m? per year)

 

Because our manufacturing process requires lower investment in production tooling, we can develop bespoke lenses and significantly lower up front cost than other lens technologies.
