Description
These are metallic “optical pins” (often used in optics/physics experiments) of length 50 mm, made of plated iron. The product is supplied in a pack of 100 g total weight
Features
Length: 50 mm. Material: Plated iron (i.e., iron pins with a plating finish) in this variant. Packaging/Weight: Pack of 100 g total. This means the set of pins weighs about 100 g. Intended Use: For optics experiments — these pins are typically used in optical benches, ray-optics setups, to serve as fixed markers/supports/spacers for light beams, lenses, mirrors etc. Finish: Plated finish (to prevent rusting/oxidation and maintain optical-bench compatibility) — “plated iron”
