Description
特に有利な実施形態では、スペクトル拡散された光のパワーを調整し、スペクトル合成するための操作要素がケーシングに直接設けられる。操作要素は操作デスクまたはパーソナルコンピュータである。調整データは電気信号の形で照明装置またはスペクトル拡散された光のパワーを変化させる装置へ送られる。具体的には、パーソナルコンピュータのディスプレイに表示され、たとえばコンピュータのマウスで操作されるスライダを介しての調整である。
微細構造光学要素は、走査顕微鏡の有利な実施形態では、少なくとも2つの異なる光学密度を有する多数の微小光学的構造要素から構成されている。特に有利な実施形態では、光学要素は第1の領域と第2の領域を有し、第1の領域は均質な構造を有し、第2の領域内には、微小光学構造要素からなる顕微構造が形成されている。また、第1の領域が第2の領域を取り囲んでいるのが有利である。微小光学構造要素は、有利にはカニューレ、細条片、ハニカム体、管片または中空空間であるのが有利である。
図1は本発明による方法のフローチャートである。第1のステップ1では、レーザーの光を微細構造光学要素に入射させる。微細構造光学要素は光をスペクトル拡散させる。この場合光は、たとえば複数のミラーにより微細構造光学要素へ誘導され、有利にはズームレンズにより微細構造光学要素にフォーカシングされる。第2のステップ3では、微細構造光学要素から出た光を照明光線に成形し、有利にはレンズシステムとして構成されたコリメート光学系を用いて成形する。次のステップ5では、照明光線を対象物へ指向させる。
