他の有機重合体を使用する場合、その使用量は、上記樹脂(β)100質量部に対して、好ましくは10~500質量部である。
加熱条件は各成分の種類及び配合割合によって異なるが、例えば、70~180℃で、オーブンなら5~15分間、ホットプレートなら1~5分間である。その後、塗膜を硬化させるために100~250℃、好ましくは180~250℃ 、より好ましくは200~250℃ で、オーブンなら30~90分間、ホットプレートなら5~30分間加熱処理することによって硬化膜を得ることができる。
本発明の波長カットフィルタは、ガラス基板(A)の一方の面に、本発明の熱反応性組成物より得られるコーティング層(B)を有し、且つガラス基板(A)の他方の面に赤外線反射膜(C)を有するものである。コーティング層(B)及び赤外線反射膜(C)はそれぞれガラス基板(A)の各面に積層されている。図1に示すように、本発明の熱反応性組成物より得られるコーティング層(B)を有する側を光の入射側としてもよく、図2に示すように、赤外線反射膜(C)を有する側を光の入射側としてもよい。以下、各層について順に説明する。
本発明の波長カットフィルタに用いられるガラス基板(A)としては、可視域で透明なガラス材料から適宜選択して使用することができるが、ソーダ石灰ガラス、白板ガラス、硼珪酸ガラス、強化ガラス、石英ガラス、リン酸塩系ガラス等を用いることができ、中でもソーダ石灰ガラスは、安価で入手容易なため好ましく、白板ガラス、硼珪酸ガラス及び強化ガラスは、入手容易で硬度が高く加工性に優れるため好ましい。
本発明の波長カットフィルタに用いられる、本発明の熱反応性組成物より得られるコーティング層(B)は、上述のように、本発明の熱反応性組成物をガラス基板(A)上に塗布することにより形成することができる。得られた塗膜は必要に応じ加熱して硬化させる。
本発明の波長カットフィルタに用いられる赤外線反射膜(C)は、700~1200nmの波長域の光を遮断する機能を有するものであり、低屈折率層と高屈折率層とが交互に積層された誘電体多層膜により形成される。
積層数は、10~80層であり、25~50層であるのが、プロセス及び強度の点から好ましい。
(i)波長430~580nmの範囲において、波長カットフィルタの垂直方向(ガラス基板の板面に対して垂直な方向、以下同様)から測定した場合の透過率の平均値が75%以上である。
(ii)波長800~1000nmにおいて、波長カットフィルタの垂直方向から測定した場合の透過率の平均値が5%以下である。
(iii)波長560~800nmの範囲において、波長カットフィルタの垂直方向から測定した場合の透過率が80%となる波長の値(Ya)と、波長カットフィルタの垂直方向に対して35°の角度から測定した場合の透過率が80%となる波長の値(Yb)の差の絶対値が30nm以下である。
波長カットフィルタにおいて、上記(i)の波長430~580nmの範囲における透過率の平均値が75%未満であると、可視光領域における光をほとんど透過しないことになる。(i)の波長430~580nmの範囲における透過率の平均値は、80%以上であることが更に好ましい。上記(ii)の波長800~1000nmにおける透過率の平均値が5%を超えると、赤外線領域における光をほとんどカットしないため、人間の視感度に近づくよう感度を補正することが困難になる恐れがある。(ii)の波長800~1000nmにおける透過率の平均値は1%以下であることが更に好ましい。
また、上記(iii)のYaとYbの差の絶対値が30nmを超えると、光の入射角による依存性が高くなり、光の入射角によって波長カットフィルタの特性が変化するため、画面の中心と周辺で色合いが変化する等の弊害が生じる恐れがある。(iii)のYaとYbの差の絶対値は5nm以下であることが更に好ましく、3nm以下であることが更に一層好ましい。
本発明の固体撮像装置は、本発明の波長カットフィルタを撮像素子の前面に備える以外は従来の固体撮像装置と同様に構成される。本発明の波長カットフィルタ1は、図5及び図6に示すように、固体撮像素子2の光入射側で固体撮像素子以外の部分に固定してもよいし、図3及び図4に示すように、固体撮像素子2の前面に直接固定してもよい。
図3及び図4は、本発明の固体撮像装置の一つであるカメラモジュールの構成の一形態を示す断面図である。カメラモジュールは、半導体基板に平面視矩形状に形成された固体撮像素子2と、固体撮像素子2の受光部3の反対側に、光入射側から染料を含有するコーティング層(B)・ガラス基板(A)・赤外線反射膜(C)の順に積層された波長カットフィルタ1(図3)/又は赤外線反射膜(C)・ガラス基板(A)・染料を含有するコーティング層(B)の順に積層された波長カットフィルタ1(図4)と、固体撮像素子2の一面において受光部3を除いた領域に形成され、固体撮像素子2及び波長カットフィルタ1を接着剤4で接合する。固体撮像装置であるカメラモジュールは、波長カットフィルタ1を通して外部からの光を取り込み、固体撮像素子2の受光部3に配置された受光素子によって受光する。
図5及び図6は、本発明の固体撮像装置の一つであるカメラモジュールの構成の一形態を示す断面図である。カメラモジュールは、半導体基板に平面視矩形状に形成された固体撮像素子2と、固体撮像素子2の受光部3の反対側に、光入射側から染料を含有するコーティング層(B)・ガラス基板(A)・赤外線反射膜(C)の順に積層された波長カットフィルタ1(図5)/又は赤外線反射膜(C)・ガラス基板(A)・染料を含有するコーティング層(B)の順に積層された波長カットフィルタ1(図6)と、固体撮像素子2の一面において受光部3を除いた領域に形成される。固体撮像装置であるカメラモジュールは、波長カットフィルタ1を通して外部からの光を取り込み、固体撮像素子2の受光部3に配置された受光素子によって受光する。
実装基板8上に固体撮像素子2を配置し、続いて、実装基板8のレンズホルダ7が固着される位置に予め接着剤4を塗布しておく。
レンズキャップ6は、レンズ5を保護するものである。また、レンズホルダ7は、レンズ5を保持するものであり、実装基板8に取り付けられて固体撮像素子2を覆う箱状のベース部7aと、レンズ5を保持する円筒形状の鏡筒部7bとを備えている。
レンズホルダ7が固定された実装基板8全体を、約85℃ で加熱して、熱硬化により更に接着剤4の硬化を十分に行ってもよい。
