⚡ At a Glance
- • Light Concentration: Concentrates sunlight across a 310mm x 310mm surface using Fresnel geometry, creating a useful focal area for heating and demonstrations
- • Best for: Hobbyists building solar cookers, schools demonstrating optics, and makers needing simple light-focusing components
- • Not ideal for: Applications requiring imaging-grade optics or precision photographic lenses
A rigid, 310mm square Fresnel lens designed to concentrate sunlight for DIY solar projects. Suits classroom demonstrations and hobby experiments that need a reliable focal spot.
Stronger focal spot - thanks to Fresnel groove design
Concentric ridges refract incoming parallel rays, bending light toward a shared focal area without thick glass. The Fresnel geometry reduces material thickness while maintaining focusing power.
Higher local intensity makes simple solar heating and focused-light demonstrations more effective and easier to achieve.
Stable handling - with rigid sheet construction
Rigid construction keeps the groove geometry flat and aligned, reducing distortion that flexible sheets can introduce during mounting. Stable geometry preserves the focal quality during use.
Easier mounting and less fiddly alignment, so setups hold their focus for longer and handle routine repositioning.
Quicker setup - with a large 310mm square area
A larger aperture reduces the precision needed to capture usable sunlight, widening the acceptable alignment tolerance. The 310mm area collects more light than smaller samples.
Faster experiments and demonstrations, suitable for outdoor classroom activities and hands-on hobby projects.
