Light Tight
Indium Foil (Light Tight) is a high-purity, flexible material with excellent electrical and thermal conductivity, specifically engineered to provide optical exclusion in sensitive research environments. Its light-tight properties make it essential in photodetectors, optical shielding, and experiments requiring minimal light interference or uniform structual integrity, such as in spectroscopy and photoelectrochemical studies. The foil is widely used in semiconductor research, where it forms low-resistance electrical contacts, and in thin-film deposition for precise material coating. Its stable performance in cryogenic environments further supports applications in low-temperature physics and thermoelectric devices, making it a versatile material for advanced R&D in optoelectronics, sensors, and energy storage laboratories.
