Description
フィルタ部分 サイズ(度)
赤 150
緑 85
青 85
赤外線 40
個々のフィルタ部分を通過する放射の区別を強化することが可能であり、この場合には、カラーホイールの赤部分26、緑部分28、及び青部分30は、実質的に全ての赤外線を遮る。同様に、実質的に全ての可視放射を遮るデータ部分32を使用するのが有利となり得る。フィルタ部分の所望の帯域通過特性は、所望のスペクトル特性を有する単一のフィルタを使用することにより、又は(例えばカラーホイール内で複数のフィルタを積層させることにより)2つ若しくは3つ以上のフィルタを組み合わせて該組み合わせたフィルタが所望のフィルタ特性を呈するようにすることにより、得ることができる。
