Hitachi High Technologies America offers Kuraray's injection compression molded PMMA Fresnel Lens for the CPV Concentrated Photovoltaic Industry. Unlike other acrylic products, Kuraray's Fresnel lens utilizes a single material, thereby eliminating the lamination process and resulting in lenses with the highest fidelity micro-replication, and 89% efficiency.

Generation 3 Fresnel Lens:

• 188mm x 188mm (552:1)
• Max. size: 1400 x 800mm
• Thickness: 4mm
• Focal length: 406mm
• Efficiency measurement with 532 nm laser: 88.8%
• Type: Injection compression molding

• Passed IEC standards
• Average Transmission change is less then 0.3%/year degradation: Accelerated test projection shows 98% transmission at 25 years with wavelength range of 350nm-150nm.
• Deflection temperature[Celsius] of a 6x5 module: 95 degrees Celsius at 65C-85%RH
