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

This Concave Mirror with a 100mm focal length is a premium‑quality optics component designed for accurate and reliable use in school physics laboratories. Carefully manufactured from optically worked glass, it provides clear, consistent reflections suitable for close‑range optical investigations.

The mirror features a vacuum‑coated silver reflective backing with an additional protective coating, ensuring excellent reflectivity, durability, and a superior optical finish. Supplied as a round, unmounted mirror, it allows flexible use with ray boxes, optical benches, and standard mirror holders.

With a compact 50mm diameter and a shorter 100mm focal length, this concave mirror is particularly well suited to small‑scale experiments and demonstrations where pronounced convergence of light and image formation can be observed over shorter distances.
