Microsharp thin film Fresnel lenses are an attractive alternative to hot embossed or injection molded lenses in High Concentration Photovoltaic (HCPV) applications.
Our proprietary lens production process provides the following benefits...
Continuous high speed production
Consistent and precise structure replication
High optical efficiency
Lower manufacturing cost
Low development and tooling cost
Lens sizes from 5mm - 400mm
Available in 'parquets up to 1m wide
Lens Construction
The Fresnel lens structure with a depth of 35 - 75 microns is produced onto the surface of a PMMA film..
The film is then bonded to the underside of a supporting PMMA sheet of between 3 - 5 mm
