Platinum/Iridium Alloy Foil (Light Tight) (Pt80/Ir20)

Platinum Iridium Alloy Foil Light Tight (Pt80/Ir20) provides a balanced combination of corrosion resistance, high-temperature capability, and mechanical rigidity while being pinhole-free to completely prevent light penetration. The thin, uniform sheet form is essential in optical isolation, high-vacuum sealing, and precision masking for photonic and semiconductor processes. Industries employ it in photolithography masks, spectrometer shielding, and as a protective layer for light-sensitive experimental setups. Research applications include fabrication of radiation shielding for detectors, optical calibration devices, and containment of photoreactive materials. The synergy of platinum’s stability with iridium’s strength, combined with the foil’s defect-free light-tightness, ensures long-term performance in demanding optical, electronic, and vacuum-based environments.
