Spinning Disk Confocal CSU

Dual Spinning Disk Confocal Technology

As the pioneer in dual spinning disk confocal technology, Yokogawa has revolutionized live cell imaging in optical microscopy. The multi-beam scanning method offers not only high speed imaging but significantly reduced phototoxicity and photo bleaching, making our confocal scanner units the de facto standard tool for live cell imaging.

High-Speed, High Resolution Imaging

Yokogawa’s confocal scanners employ advanced imaging technologies to help researchers achieve high-speed and high-resolution live cell imaging.

Fast time-lapse confocal images of living cells
Minimal phototoxicity and less photobleaching
Live-cell confocal fluorescence imaging capabilities
Stability during long-term and high-speed imaging
Facilitates quantitative analysis of huge amounts of data

Super Resolution
