Description
また上記構成において、前記樹脂ホルダの面の膨張により前記位置調整用の隙間を小さくするとともに、前記位置調整用の隙間の範囲内で前記光学部品を相対的に移動させ、前記光学部品と前記樹脂ホルダとを接合させることを特徴とする。前記光学部品を移動させて前記膨張した樹脂ホルダの面と接触させ、前記接触後に前記光学部品と前記樹脂ホルダとを接合させることを特徴とする。前記光学部品を前記膨張した樹脂ホルダの面と接触させた後に、前記光学部品を位置調整し、前記位置調整後に光学部品と前記樹脂ホルダとを接合させることを特徴とする。
(第1実施形態)
図1は本発明の第1実施形態におけるレーザ接合方法の実施状況を示す断面図、図2は同レーザ接合方法の実施時の接合対象物の変化を示す一部拡大断面図である。
そこで、光学部品3を樹脂製ホルダ2に固定するために、以下の温度関係(式2)を満たすように樹脂製ホルダ2にレーザ光9を照射して樹脂を昇温させる。式中、Txは樹脂製ホルダ2を構成する樹脂の溶融温度、Tyは同じく分解温度である。
この場合、表層部13の温度T13は溶融温度Txよりも高いため表層部13の樹脂は液化する。またレーザ照射部11、内層部12の温度T11、T12は分解温度Tyよりも高いため、レーザ照射部11、内層部12の樹脂は分解し、樹脂中に含まれる例えば炭素原子や酸素原子が結合して二酸化炭素などのガスが発生する。
(第2実施形態)
図4は本発明の第2実施形態におけるレーザ接合方法の実施状況を示す断面図である。この第2実施形態が第1実施形態と相違するのは、樹脂製ホルダ2が、水平方向(紙面左右方向)に振動する振動ステージ15上に設置されている点である。
(第3実施形態)
図6は本発明の第3実施形態におけるレーザ接合方法の実施状況を示す断面図である。この第3実施形態が第1実施形態と相違するのは、図6(a)に示すように、レーザ光9による溶融部分10に向けて窒素ガス17を噴出可能な複数のノズル16を設けた点である。
(第4実施形態)
図7は本発明の第4実施形態におけるレーザ接合方法の実施状況を示す断面図である。この第4実施形態が第1実施形態と相違するのは、図示したように、レーザ光9による溶融部分10に向けて音波を供給可能な音波発生装置18を設けた点である。
