捕获低亮度荧光和大视野图像
高分辨率、高灵敏度和低噪声是DS-Qi2单色相机的关键特征。
Description
超大尺寸CMOS传感器
尼康为专业高端单反相机设计、生产的CMOS传感器和成像技术，现在已经为显微镜成像进行了优化。
高灵敏度
可探测微弱的荧光信号
7.3μm像素尺寸，高量子效率QE和非常低的读取噪声，允许DS-Qi2甚至探测非常微弱的荧光信号。

出色的线性表达
可靠的定量分析成为可能
DS-Qi2线性误差为±1％，是测量荧光样品强度的绝佳工具，包括基于时间的强度测量和比例测量。
高帧速率
即使荧光图像也可快速对焦
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，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.
