Principles of Spinning disk confocal

 

最常見的傳統共軛焦顯微鏡使用單個雷射光束掃描樣本, CSU 使用增強的 Nipkow 盤掃描,使用大約 1,000 束雷射光束掃描視野:簡而言之,CSU 的掃描速度可以提高 1,000 倍。

通過將包含微透鏡陣列的磁盤與 Nipkow 磁盤結合使用,顯著提高光效率,能成功使活細胞的即時共軛焦成像成為可能。

經擴展和準直的激光束照射包含約 20,000 個微透鏡(微透鏡陣列盤)的上盤。每個微透鏡將激光束聚焦到其相應的針孔上,從而通過放定在針孔陣列盤(Nipkow 盤)中的針孔有效地增加激光強度。

使用微透鏡,可以顯著減少針孔盤表面的雷射光背向散射而顯著提高共軛焦圖像的訊號雜訊比 (S/N)。

每個針孔大約 1,000 束雷射光束填充物鏡的孔徑,然後聚焦在軛焦平面。樣品產生的螢光被顯微鏡獲取並聚焦回針孔盤上,通過相同的孔傳輸消除離焦信號,由位在微透鏡陣列盤和 Nipkow 盤之間的分色鏡偏轉以分裂螢光來自反射雷射的信號,發射濾光片,然後聚焦到目鏡或相機中的圖像平面。

微透鏡陣列盤和 Nipkow 盤在物理上相互固定並旋轉以高速掃描整個視野,從而可以通過 CSU 的目鏡即時查看共軛焦螢光圖像。

與傳統的單點掃描相比,CSU 的多光束掃描需要非常低的單位面積光強度,顯著降低活細胞中的光漂白和光毒性。

摘要:

The CQ1 confocal image acquisition mechanism with the distinctive CSU® unit has a function to sequentially acquire fine cell images along the Z-axis and capture information from the entire thickness of
cells which include heterogenic populations of various cell cycle stages. In addition, saved digital images can be useful for precise observation and analysis of spatial distribution of intracellular molecules.
The CQ1 capability to seamlessly analyze images and obtain data for things such as cell population statistics to individual cell morphology will provide benefits for both basic research and drug discovery
targetingM-cell cycle phase.
