LIGHT GUIDE ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a light guide element which simultaneously satisfies the lowering of cost and the enhancement of performance. SOLUTION: At least one of a core and a clad constituting the light guide element is formed from a polymer film obtained by polymerizing a polymerizable blend including at least one reactive oligomer of formula (I) [where Y is H or CH3 and Rf is selected from groups of formulae (a) and (b) and the formula -CH2(CF2)mCH2- (c) (where (m) is an integer of 2-10)].
