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 via Optical Re-assignment.
The CSU-W1 is our answer to researchers’ requests for “Wider FOV” and “Clearer Images”.
The CSU-X1 is widely recognized as the leading tool for live cell imaging with 2,000 fps capability.
