空间用抗辐照玻璃盖片, 用于太空飞行器上硅太阳能电池表面的防护材料. Antiradiation coverglass for silicon solar cells on spacecraft. Source intro (p.113) states there are two glass grades in this section, KFB and BF, but only KFB technical-index tables were found in the scanned pages (in two thickness variants, 0.12mm and 0.3mm, with different spec values and irradiation test conditions — see also code KFB-0.3mm). No dedicated BF technical-index table, curve, or property table was located in either source PDF; treat BF as unconfirmed/not transcribed pending better source pages. Density given as a range (2.51~2.58); midpoint used for physicalProperties.density. Curve re-digitized from clean-scan PDF chart (booklet p.114, curve labeled 'KFB'): confirmed the left edge genuinely reads ~0% up to the UV cutoff near 320-330nm (matches spec ≤1.0% at 330nm) — this is a real cutoff, not a digitization default. Plateau (500-2500nm) reads visually flat at ~92% with only a very gentle IR-tail decline toward 2500nm; anchor points at 400nm/450nm/500-1100nm cross-checked against the technical-index table.
