Cross Pointer (only) of metal wire

**Cross Pointer (Metal Wire – Only)**

A simple yet precise laboratory accessory made from thin, rigid metal wire shaped into a symmetrical cross. Each arm of the cross is straight and evenly spaced, typically measuring 5–10 cm in length. The wire is polished for visibility and corrosion resistance, often made from stainless steel or nickel-plated brass. Used in physics experiments to mark the center of optical paths, align apparatus, or demonstrate principles of symmetry and refraction. Lightweight, durable, and easy to mount on stands or optical benches.
