The optical material in accordance with the present invention contains a specific phosphonate monoester compound such as monoethyl 3-methoxy butyl phosphonate, and a metal ion such as a copper ion or rare-earth metal ion. They may be contained in a solvent or resin. The use of such a specific phosphonate monoester compound improves the compatibility with a resin, whereby the metal ion can favorably be dispersed into the resin. Consequently, spectral characteristics can be improved when the optical member is formed into a resin-made optical member.
本发明的光学材料含有一种特定的

酯类化合物(如 3-甲氧基丁基
膦酸单
乙酯)和一种
金属离子(如
铜离子或稀土
金属离子)。它们可以包含在溶剂或
树脂中。使用这种特定的
膦酸单
酯类化合物可提高与
树脂的相容性,从而使
金属离子能更好地分散到
树脂中。因此,当光学部件被制成
树脂制光学部件时,其光谱特性可得到改善。
