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。

绝佳的线性特性
----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个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，使获取的荧光图像具有极低的噪声和极高的动态范围。

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绝佳选择。
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.
