Description
Fresnel Lens – Large 8"x10" Educational Optical Lens, 3x Magnification
This large Fresnel lens is designed for classroom demonstrations and educational use in optics and light behavior. Originally developed for use in lighthouses, Fresnel lenses are engineered to provide a large aperture and a short focal length with significantly less material than conventional convex lenses.
This model measures 8 inches by 10 inches, is approximately 2mm thick, and offers 3x magnification. Its thin, lightweight construction allows it to capture more oblique light from a source, making it ideal for demonstrating key optical principles such as refraction, magnification, and light focusing efficiency. The lens is well-suited for classrooms, science labs, homeschool environments, and physics education settings.
Key Features
- Lightweight and Efficient: Captures oblique light better than standard lenses for clear magnification demonstrations.
- Large Format: 8 x 10 inches for a wide viewing area.
- Slim and Portable: Approximately 2mm thick for easy handling and storage.
- 3x Magnification: Effectively demonstrates refraction and light bending.
- Educational Use: Ideal for optical experiments in science and physics classrooms.
