Ultima 2Pplus
憑藉在視野、靈敏度、波長和樣品調節方面的新進步,Ultima 2Pplus 提供了靈活性、分辨率、成像深度和速度的理想組合,使用戶能夠以更高的效率和效果同時執行成像、刺激和電生理學實驗。
該系統專為活體成像而設計,物鏡可進行 X-Y-Z 三軸的全方位電動控制,以及兩個旋轉軸以實現精確的成像定向。第二個掃描路徑可以同時進行成像和光刺激。該系統最佳化的光學系統可為使用者帶來極大的視野。
看得更廣
更廣的視野範圍讓您能夠掌握整個區域的影像動態
看得更深
可進行組織更深度的掃瞄,不放過任何一個維度
看得更小
即使是單一細胞的活化訊號也能夠瞭若指掌
產品特色
最大的視野和卓越的視野均勻性
與其他類似的雙光子顯微鏡產品相比, Ultima 2Pplus 的視野擴大了 50% 以上,有利於現代光遺傳學實驗,這些實驗需要同時對樣本中的遠處區域進行成像和光刺激。新的客製化光學設計可以保留整個領域的空間和時間分辨率,這對於研究人員能夠在不改變實驗設計的情況下繼續他們的工作至關重要。

Field of view on Ultima 2Pplus is FN 28 mm in comparison to industry standard of FN 18 mm.
高靈敏度深層成像
Ultima 2Pplus 光的收集可確保含蓋幾乎所有從暗淡、厚實和不透明的生物樣品中散射出的光子。2 英吋或更大的光學元件構成的探測器可提供您卓越的收集效率。隨著雙光子顯微鏡的廣泛採用,新興的三光子顯微鏡提供了對樣品進行更深度成像的潛力。由於更遠的紅外線波長被散射得更少,三光子激發有望能夠在大腦中幾毫米處成像。 Ultima 2Pplus 已獨特地整合了此功能,可將您的研究潛力提升到新的境界。

完美的光刺激和成像
Ultima 2Pplus 可透過 Bruker 的全新 Neuralight 3D 超空間光調製器 選配來進行更複雜的光遺傳學實驗。可以使用電腦生成的全像圖在多個焦平面上同時刺激大量目標。在 3D 全像實驗期間,使用客製化設計的光學校正 ETL 聚焦模組對不同深度的目標進行成像,該模組允許成像平面相對於光刺激的獨立 Z 定位。
