Description
集束光学部品28は、集束光学部品32、34、36、38、および40とともに、焦点距離の構築を担う開口絞り22よりも前方に位置する光学部品からなる前方グループを構成する。焦点距離は、画像形成装置10に入射するビーム16の開口数とともに、開口絞り22の直径を設定する。図1から明らかな長い焦点距離は、物点20に対応する主光線18および周縁光線17または19を、互いに相手に対して最小の角度を通って集束させるようになっている。対応する光線が交差する開口絞り22近傍において、集束光学部品32の前からビーム16がマンジャンミラー50に入るまで、対応する光線17、18,または19の放射方向の著しい発散は発現しない。よって、対応する光線17、18,または19がほぼ重なり合う瞳孔スペース46が、開口絞り22の両側に十分に延びている。
