Description:

Livingstone Bi-Concave Lens offers precise optical performance for scientific, laboratory, and educational applications. Manufactured from high-quality glass, this lens features a 50mm diameter and a 15cm focal length, designed to diverge light rays and expand beam width in optical setups. Its smooth curvature and clarity support experiments involving focal adjustments, imaging systems, and physics demonstrations. Supplied individually, the lens is ideal for use in optical benches, refractive index studies, and custom visual equipment requiring accurate beam dispersion.
