Plano-Convex Glass Lens, 50mm Diameter, 100mm Focal Length

This Eisco Labs Plano-Convex Lens measures 50mm in diameter with a 100mm focal length. The lens features one flat side and one convex side, with a refractive index of 1.51–1.52. Plano-convex lenses are commonly used in physics experiments to focus light, form images, and demonstrate refraction. The 50mm diameter provides a useful aperture for optical bench work. Suitable for physics classrooms studying lens optics, focal length determination, and image formation.
