Reach out regarding the development of sample lenses for a new solar concentration application. Looking for a lens design that can eliminate the need for mechanical sun - tracking systems, highly efficient and cost - effective. The concept is similar to AGILE. Key characteristics: design resembles an inverted pyramid with a flat top and truncated point; maintains a static focal point as the sun moves; efficiency goal of capturing and concentrating a high percentage of incident light; ideally made of Silica Glass; with graded index and layered construction; dimensions typically range from 3mm to 28.6mm in total height, layer thicknesses from 0.2mm to 3mm (initial test); materials must have compatible thermal expansion coefficients and maintain the graded index shape. Ask if the company can work with these specifications for sample development.
