W-VIEW GEMINI イメージスプリッティング光学系
W-VIEW GEMINIは、入射光を2波長に分光し、1台のカメラに結像させる蛍光顕微鏡用イメージスプリッティング光学系です。2波長の画像を1画面で同時に観察することができます。
W-VIEW GEMINIは、蛍光イメージングで使用される様々な蛍光タンパク質や試薬の検出波長である400 nm~800 nmの広い波長範囲において高い透過率を実現していますので、より暗いサンプルの検出やより弱い励起光での観察が可能になりました。
W-VIEW GEMINIは、有効視野が従来品のW-View光学系(A8509)のφ10 mmから13 mm×13 mmへと広がりました。これによりsCMOSカメラ ORCA-Flash4.0 シリーズと組み合わせることで、片波長において13 mm×6.4 mmの広視野かつ約2000画素×1000画素の高画素数イメージングが可能になりました。
W-VIEW GEMINIでは、市販のダイクロイックミラーが使用可能になり、2波長の選択の自由度が広がりました。また、バンドパスフィルタやNDフィルタも市販品が使用可能なため実験に応じた光学部品の選択ができます。
W-VIEW GEMINIは、本体とカメラを顕微鏡に取り付けたままダイク ロイックミラー等を取り外して、カメラを顕微鏡のポートに直接取り付 けた場合と同様な状態に設定できるバイパスモード機能を有していま す。この機能があることで、別の実験のために簡単に顕微鏡とカメラ を使うことができ、さらに簡単に元の実験の状態に戻すことが可能になります。
W-VIEW GEMINIには、補正レンズユニットが長波長側の光路に搭載され、2波長の画像の色収差で生じる倍率の差を改善することができます。(画像は、色収差による倍率の差が補正レンズユニットによって改善されている例を示します。)
W-VIEW GEMINIは、入力と出力のCマウントが直線状に配置されていることや従来品のW-View光学系(A8509)に比べサイズがコンパクトになったことにより、正立顕微鏡でもバランス良くご使用いただけます。
W-VIEW GEMINIは、シンプルな構造に設計されているために、位置調整箇所が少なく、設置時における研究者の手間を軽減することができます。また、当社カメラと組み合わせて使用する場合には、カメラに付属する専用調整ソフトウエア「W-VIEW Adjustment」を使用することで、さらに素早く簡単に位置調整を行うことができます。(画像は専用ソフトウエアで中央、周辺の9か所のみを拡大した画像を映し出し、位置調整を行い易くする機能を示しています。)
