Multiple functions fully integrated in a compact box

Compact design contains fully integrated multiple functions to offer easy-to-handle confocal imaging system, without a need for complicated system integration; you only need to set a sample and run the software. User-friendly interface and versatile functions support your measurement and analysis.


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.

Application Note
Application Note

The CQ1 confocal image acquisition mechanism with the distinctive CSU® unit has a function to sequentially acquire fine cell images along the Z-axis and capture information from the entire thickness of
cells which include heterogenic populations of various cell cycle stages. In addition, saved digital images can be useful for precise observation and analysis of spatial distribution of intracellular molecules.
The CQ1 capability to seamlessly analyze images and obtain data for things such as cell population statistics to individual cell morphology will provide benefits for both basic research and drug discovery
targetingM-cell cycle phase.

Application Note

Cell stage categorized using FucciTime lapse imaging of Fucci-added Hela cells was conducted over 48 hrs at 1 hr intervals. Gating was performed based on the mean intensities of 488 nm and 561 nm for each cell. They were categorized into four stages, and the cell count for each was calculated.
