Commodity: Metals Material: Praseodymium Form: Foil (Light Tight) Composition: Pr CAS Number: 7440-10-0 Purity: 99% Temper: As Rolled Opacity: Light Tight
Praseodymium Foil (Light Tight) offers the same corrosion resistance, ductility, and unique magnetic and optical characteristics as standard praseodymium foil, but with a surface free of pinholes, blocking all external light transmissions. This makes it ideal for optical, photonic, and scientific environments where both rare-earth material properties and absolute light exclusion are essential. Industries use it for precision light-blocking baffles, thin-film deposition masking, and photonic shielding components. Specific applications include shielding sensitive optical detectors in spectroscopy, blocking stray light in astrophysical instruments, and forming light-tight enclosures for photonics research. In experimental setups, it enables studies that demand complete optical isolation combined with the performance advantages of a rare-earth foil. This specialized combination of material characteristics and guaranteed light-blocking capability makes it a critical choice for high-precision industrial and research applications.
