Description
図1は、第1の実施の形態に係る光測定装置の概略の構成を示す図である。本実施の形態による光測定装置の本体部分の基本的な装置構成は共焦点光学顕微鏡をベースとしている。以下、図1を参照しつつ、光測定装置の構成と動作について説明する。
第1の実施の形態の変形例1では、計測時に光位置検出器の電源をOFFし、計測終了で光位置検出器の電源をONするという動作は第1の実施の形態と同じだが、光測定装置のロジック回路を用いてその判断を行う点が異なっている。
第1の実施の形態の変形例2では、計測時に光位置検出器の電源をOFFし、計測終了で光位置検出器の電源をONするという動作は第1の実施の形態と同じだが、光測定装置本体に光位置検出器の電源をオン、オフできるスイッチを設け、光学調整時には光位置検出器の電源をON、測定時には光位置検出器の電源をOFFという動作をオペレーターが手動で行なう。
以上説明した構成の光測定装置を用いて、光軸調整完了後、試料ステージ9にマイクロプレート8を設置し、ウエルに緩衝液(PBS:リン酸バッファー液)(蛍光物質は入っていない)を収容し、ヘリウム・ネオンレーザ(波長:633nm, 出力300μW)を照射した。この時得られる光検出器26からの出力値(カウントレート)を測定した。
光位置検出器による光学素子の位置や角度を検出し位置調整を行うため、複数の光源を用いた複雑な光学系の配置が可能であり、その際生じるノイズ光をカットすることができるので、精度の高い測定ができる。
