Abstract
(EN)
A fiber optics plate 122 comprises: a plurality of core glass pieces 122a; cladding glass 122b that covers the core glass pieces 122a; and light-absorbing glass pieces 122c disposed between the plurality of core glass pieces 122a. The TiO2 content in the core glass pieces 122a is 7 mass% or less, the B2O3 content in the core glass pieces 122a is 15 mass% or greater, and the WO3 content in the core glass pieces 122a exceeds 0 mass%.
