Convex Mirror – 100mm Focal Length (50mm Diameter)

This Convex Mirror with a 100mm focal length is a premium‑quality optical component designed for accurate and repeatable use in school and college physics laboratories. Manufactured from precisely optically worked glass, it delivers clear and reliable reflection performance for teaching and learning.

The mirror incorporates a vacuum‑coated silver reflective backing with a durable protective surface coating, providing excellent reflectivity and long‑term resistance to wear. Supplied as a round, unmounted mirror, it can be easily positioned in mirror holders, optical benches, or ray‑box setups.

With a compact 50mm diameter and a shorter 100mm focal length, this convex mirror clearly demonstrates the divergence of light rays and the formation of diminished, virtual images, making it particularly effective for close‑range classroom experiments.
