Pyrolytic Graphite Carbon Foil (Light Tight)

Pyrolytic Graphite Carbon Foil (Light Tight) is a dense, opaque form of pyrolytic graphite with excellent light-blocking and vacuum-sealing performance. Manufactured via chemical vapor deposition and high-temperature annealing, it exhibits anisotropic thermal conductivity, ultra-low gas permeability, and exceptional radiation resistance. Its light-tight variant is optimized for shielding sensitive optical systems from stray light and is used extensively in X-ray optics, neutron moderation, synchrotron diagnostics, and high-energy physics instrumentation. The foil’s structural coherence along the basal planes supports high-resolution X-ray diffraction, while its impermeability ensures reliable sealing in vacuum systems. It plays a critical role in protecting detectors, enabling precision optics alignment, and minimizing background signals. In research and industry, this material bridges structural stability with functional shielding, making it indispensable for radiation shielding, photonic isolation, and advanced beamline engineering.
