单色显微镜数码相机

DS-Qi2

弱荧光拍摄与宽视野

      DS-Qi2单色相机具备高像素密度、高灵敏度与低噪声的特性。

 | 超大规格CMOS传感器

       继承自专业数码单反相机并由尼康制造的CMOS传感器和成像技术，经过优化现已用于显微技术。
高灵敏度  可检测微弱荧光信号
       7.3um像素尺寸，高量子效率配合低读出噪声使DS-Qi2甚至可以检测微弱的荧光信号。

 | 的线性特性 
      可实现可靠的定量分析

       ± 1%的线性误差，DS-Qi2是荧光强度测量的绝好工具。无论时间强度测量还是比率测量都可轻松应对。

 | 高帧率 
      即使使用荧光图像亦可实现快速对焦

      2.2个电子读出噪声配合大容量像素及0.6电子暗电流使其可以拍摄极小噪声的荧光图像。

 | 低噪声
      获取微弱荧光的极低噪声图像

        2.2个电子读出噪声配合大容量像素，是获取的荧光图像具有极低的噪声和*的动态范围。

 | 时间序列成像    
      使用NIS-Elements软件进行荧光时间序列成像

       结合宽视野和高像素密度及低噪声，DS-Qi2是时间序列拍摄应用的选择。 

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.
