Platinum/Iridium Alloy Foil (Light Tight) (Pt90/Ir10) - T 2mm 10mm x 10mm

Details

SKU: 1000164004 Product Code: PT02-FL-000250
Platinum Iridium Alloy Foil Light Tight (Pt90/Ir10) combines exceptional corrosion resistance, mechanical strength, and stability at elevated temperatures with a pinhole-free structure to ensure total light exclusion. This makes it indispensable in high-vacuum optical systems, radiation shielding for sensors, and precision photolithography. Industries rely on it for electron beam equipment components, optical device isolation layers, and protective sheaths for light-sensitive electronics. Research uses include development of photonic test environments, creation of defect-free reflective surfaces, and shielding for spectroscopy equipment. The integration of platinum’s noble metal resilience and iridium’s hardening effect with a flawlessly light-tight foil format delivers exceptional durability, optical integrity, and stability for advanced scientific and engineering applications.
