Description
本発明の組み合わせレンズの製造方法によれば,紫外線吸収能を有する透明樹脂レンズを用いているので,溶着による接合は容易である。
このようにすれば,この組み合わせレンズの製造は容易である。
このようにすれば,比較的少ない回数の光線照射によって組み合わせレンズを製造できる。
さらに本発明では,溶着のために照射する光線は,紫外線レーザであることが望ましい。
このようにすれば,接合箇所に的確に光線を照射することができる。逆に,溶着のために照射する光線は,紫外線吸収剤によって吸収され得る光線であればよく,必ずしも紫外線でなくてもよい。紫外線吸収剤は,紫外線だけでなく,比較的短波長の可視光線に対しても吸収能を有する場合がある。この場合は,紫外線吸収剤に吸収され得る可視光線を照射しても,溶着させることができる。
さらに,他の透明樹脂レンズとして,溶着のために照射する光線を吸収することなく透過させるものを用い,溶着のために照射する光線を,他の透明樹脂レンズを透過して第1透明樹脂レンズの周辺部に照射することが望ましい。
以下,本発明を具体化した第1の形態について,添付図面を参照しつつ詳細に説明する。本形態は,複数枚の光学レンズを組み合わせた光学レンズ組に本発明を適用したものである。
次に,本発明を具体化した第2の形態について,添付図面を参照しつつ詳細に説明する。本形態は,CCD等の固体撮像素子を有するカメラ等に用いられる光学レンズ組であり,3枚以上の光学レンズを有する光学レンズ組に本発明を適用したものである。
例えば,上記の各形態に示した各レンズや鏡筒の形状や個数は一例であり,用途等に応じて適宜変更可能である。
また例えば,接合部L1,L2の配置や個数も適宜変更可能である。また,紫外線レーザを照射しつつレーザヘッドを円周状に移動させてもよい。
また例えば,溶着のために照射する光線は,紫外線吸収剤によって吸収される光線であればよく,必ずしも紫外線レーザでなくても良い。
また例えば,各レンズのいずれかに赤外線を吸収する吸収剤をさらに含有させれば,そのレンズによって赤外線カットフィルタの機能をも兼ねさせることができる。このようにすれば,赤外線カットフィルタが不要となるので,さらなる小型化が可能となる。
