Iron/Chromium Foil (Light Tight) (Fe95/Cr5)

Iron Chromium Foil Light Tight (Fe95/Cr5) offers high structural integrity, oxidation resistance, and a finely balanced alloy composition that ensures pinhole-free shielding against all external light transmissions. Its performance as a light-tight foil is critical in photonics, vacuum chambers, and imaging systems where stray light must be completely eliminated. Industrial applications include aerospace optical housings, protective linings for spectrometers, and shielding for microscopy setups. In research, it is used for photodetector isolation, calibration of light-sensitive instruments, and controlled optical testing. The foil’s machinable format allows ease of integration into enclosures while maintaining full light exclusion and environmental durability. Its unique combination of light-blocking reliability and chromium-enhanced corrosion resistance ensures long-term functionality in demanding scientific and engineering environments.
