6-Piece Acrylic Lens Set, 38mm (Convex, Concave, Plano, Meniscus)

This six-piece acrylic lens set contains spherical lenses measuring 38 mm (1.5 inches) in diameter. The set includes one double convex (20 cm FL), one double concave (20 cm FL), one plano convex (25 cm FL), one converging concave-convex (25 cm FL), one diverging concave-convex (25 cm FL), and one plano-concave (25 cm FL). Each lens has brushed edges and a polished face. The lenses are stored in a hinged wooden box with foam inserts to keep them secure. This set provides a comprehensive range of lens types for optics experiments in physics classrooms, including demonstrations of focal length, image formation, convergence, and divergence.
