CSU-X1 and CSU-W1

Spinning disk confocal imagers from Yokogawa Electric Corporation

The Confocal Scanner Unit is an industry standard for life science imaging. BioVision offers many unique modifications on new turnkey systems or upgrades for exisiting labs.

Upgrades to the CSU10, the CSU-21, the CSU-22, or the CSU-X1 Spinning Disk Confocal Imager

BioVision Technologies offers significant upgrades to an existing CSU10, CSU-21, CSU-22, or CSU-X1 confocal imager. Suitably upgraded and incorporating a Nipkow spinning disk, the CSU acquires confocal images at video rates, minimizing photobleaching and phototoxicity – ideal characteristics for live cell work.

Optional Laser Merge Module
For applications requiring multiple excitation wavelengths, BioVision Technologies combines the CSU with laser laser merge modules from leading manufacturers. Lasers are available in a range of wavelengths and powers.
Optional Emission Filter Wheel
BioVision Technologies offers and supports filter wheels from Ludl Electronics Products, Prior Scientific and Sutter Instrument Company.

CSU-X1 Spinning Disk Confocal Imager

BioVision Technologies offers the CSU‐X1 confocal imager. Incorporating a Nipkow spinning disk, it acquires confocal images with minimal photobleaching and phototoxicity, making it ideal for live cell work.

Basic and High‐end models are available. The Basic model offers a fixed‐speed scanner motor, while the High‐end model offers a variable speed motor.

The imaging speed of the Basic model matches that of the CSU-10, while the High-end model offers almost seven times that speed.

Its filter wheel switches between adjacent positions in 33 ms.

CSU-W1 Spinning Disk Confocal Imager

BioVision Technologies offers the CSU‐W1 confocal imager. Incorporating a Nipkow spinning disk, it brings a wider field of view and clearer images to the Yokogawa Electric CSU line.

Features of the CSU‐W1

  • Wide field of view: four times that of the conventional model of CSU (CSU10, CSU‐21, CSU‐22, CSU‐X1)
  • Clearer images: a newly‐designed disk unit offers significantly reduced pinhole crosstalk, enabling clear observation much deeper into thick samples.
  • Near Infrared (NIR) Port : Up to 785 nm
  • Available in one‐camera, two‐camera and split‐view models
  • Brightfield imaging provided with all CSU‐W1 units, via motorized mechanism for moving disks out of light path
  • Pinhole size options: 25 µm pinhole disk, 50 µm pinhole disk, or dual disk with motorized disk exchange mechanism
  • External light path
  • 10-position filter wheel(one‐camera model, two‐camera model)

VS-Homogenizer for the CSU-W1 Spinning Disk Confocal Imager

BioVision Technologies offers the VS-Homogenizer optical component from Visitron Systems GmbH. It is designed to enhance the laser illumination of the CSU-W1.

This enhancement offers even illumination of large cell areas and allows high-sensitivity imaging of living cells without the need for mathematical shading correction.

This optical component can be added on request to CSU-W1 confocal scan heads that have already been installed.
