he Concave Optical Lens 50mm Double is a high-quality laboratory lens designed for optical experiments, light refraction studies, and educational demonstrations. Made from optically clear glass, this lens provides precise light control and distortion-free imaging. Because of its double concave design, it diverges light rays passing through it, creating clear and measurable optical effects that are essential for physics and optics experiments.

This 50mm double concave lens is carefully polished and edge-finished to ensure maximum accuracy in classroom or laboratory applications. It’s widely used in schools, colleges, universities, and research laboratories for demonstrating the behavior of light through lenses. The lens’s uniform curvature allows consistent results in experiments involving image formation, focal length determination, and ray tracing.

Its durable glass construction ensures excellent performance and resistance to scratches or minor impacts. Furthermore, the lens has a 50mm diameter, which makes it ideal for use with various optical benches, light sources, and spherometers used in scientific experiments.
