Concave Mirror – 150mm Focal Length (50mm Diameter)

This Concave Mirror with a 150mm focal length is a premium‑quality optical component designed for accurate and repeatable use in school and college physics laboratories. Manufactured from carefully optically worked glass, it provides clear, distortion‑free reflections for teaching and demonstrating fundamental optics principles.

The mirror incorporates a vacuum‑coated silver reflective backing with an additional protective coating, delivering excellent reflectivity along with long‑term durability. Supplied as a round, unmounted mirror, it can be used flexibly with optical benches, ray boxes, and standard mirror holders.

With a compact 50mm diameter, this concave mirror is easy for students to handle and is ideal for close‑range optics experiments where a shorter focal length is required to clearly observe image formation and light convergence.
