單色顯微鏡數(shù)碼相機

DS-Qi2

弱熒光拍攝與寬視野

      DS-Qi2單色相機具備高像素密度、高靈敏度與低噪聲的特性。

 | 超大規(guī)格CMOS傳感器

       繼承自專業(yè)數(shù)碼單反相機并由尼康制造的CMOS傳感器和成像技術(shù)，經(jīng)過優(yōu)化現(xiàn)已用于顯微技術(shù)。
高靈敏度  可檢測微弱熒光信號
       7.3um像素尺寸，高量子效率配合低讀出噪聲使DS-Qi2甚至可以檢測微弱的熒光信號。

 | 的線性特性 
      可實現(xiàn)可靠的定量分析

       ± 1%的線性誤差，DS-Qi2是熒光強度測量的絕好工具。無論時間強度測量還是比率測量都可輕松應(yīng)對。

 | 高幀率 
      即使使用熒光圖像亦可實現(xiàn)快速對焦

      2.2個電子讀出噪聲配合大容量像素及0.6電子暗電流使其可以拍攝極小噪聲的熒光圖像。

 | 低噪聲
      獲取微弱熒光的極低噪聲圖像

        2.2個電子讀出噪聲配合大容量像素，是獲取的熒光圖像具有極低的噪聲和*的動態(tài)范圍。

 | 時間序列成像    
      使用NIS-Elements軟件進(jìn)行熒光時間序列成像

       結(jié)合寬視野和高像素密度及低噪聲，DS-Qi2是時間序列拍攝應(yīng)用的選擇。 

Time-lapse images (every 1 second) of LLC-PK1 cells with GFP-EB3 tubulin. Each image represents the maximum intensity projection of the timelapse, allowing visualization of the end-binding protein located on the microtubule plus-ends, and allowing tracing of the microtubule path.
DS-Qi2 captures an extremely large field of view, but still represents very fine details as demonstrated in this cropped timelapse sequence from a large FOV image.
