Reduction of fluorescent cross-talk

Fluorescent cross-talk is an artifact caused by fluorescent signal that is superimposed on other fluorescent color(s) in simultaneous multi-wavelength fluorescent image acquisition.
This artifact can be reduced by image processing.

Wide-view confocal scanner unit

Microlens-enhanced dual Nipkow disk technology significantly reduces photobleaching and phototoxicity in live cell imaging

Principles of the Microlens-enhanced Nipkow Disk Scanning Technology

A Nipkow spinning disk containing about 20,000 pinholes and a subsidiary spinning disk containing the same number of microlenses to focus excitation laser light into each corresponding pinhole are mechanically fixed on a motor, and very rapidly rotated. As a result, high-speed raster scan of the excitation lights on the specimen can be achieved.The pinhole and microlenses are arranged on each disk in our proprietary design to optimize raster scan.
Multi-beam scanning not only increases scanning speed, but also results in significantly lower photobleaching and phototoxicity, because multi-beam excitation needs only low level of laser power on the specimen to fully excite fluorescence.
CV7000 uses wide-view Nipkow disk model which is capable of scanning 4 times wider imaging area with higher resolution and thus capable of ultrafast and high-resolution screening.
