Name: CSU-W1 Confocal Scanner Unit
Brand: Yokogawa
SKU: csu-w1-confocal-scanner-unit

Widest field of view in the industry providing 4X wider FOV than conventional scanners.

The CSU-W1 Confocal Scanner Unit is our widest field of view confocal, providing the clearest image resolution of our imaging systems. The system features switching mechanisms to enable fully automated experiments and a newly designed disk unit to improve image clarity of thick samples.

Wide

Widest FOV confocal! Provides 4 times wider FOV than the conventional model.

Widest FOV confocal

Clear

Newly designed disk unit offers much improved image quality. Due to significantly reduced pinhole crosstalk, CSU-W1 enables clear observation much deeper into thick samples.

Flexible

Flexibly selectable functions to meet versatile applications.

High confocality pinhole (Optional Component)

In addition to our conventional 50um pinhole size, 25m pinhole size with higher confocality is available.
You can select either one or the both pinhole size, with easy-to-use motorized disk exchange mechanism.

Disk unit

New bright field through path (Standard)

New mechanism to move the disks out of the light path allows much easier projection of confocal and non-confocal images such as phase contrast.

Simultaneous dual color imaging mechanisms
(T2 and T3 Models)

CSU-W1 offers single camera split-view model, in addition to the dual camera model which are much improved from those for the CSU-X1. Thanks to the wide FOV, even the split-view offers 2 times wider image area than with older model. By using various dichroic mirrors, it is possible to select various dye-combinations for dual-color imaging^*1 with both the two camera model and split-view model.

CSU-W1 offers selection from a total of three basic configurations, two pinhole sizes, options for near infrared observation and an external light path which is useful for versatile applications such as photo bleaching, while bright field light path is now a standard feature. All switching mechanisms in the CSU-W1 are fully motorized and thus ready for automated experiments.

Basic Configurations

CSU-W1 provides a total of three basic configurations for multi- color imaging; 1) Sequential imaging with one camera and a filter wheel, 2) Simultaneous two-color imaging with two cameras, and 3) Split-view two color imaging with one camera shared by 2 optical paths. All features are upgradable after installation.

Basic Configurations

Filter

Option

SoRa disk

Optical resolution has been improved by approximately 1.4x using a super-resolution technique based on spinning-disk confocal technology. Furthermore, a final resolution approximately twice that of the optical limit is realized through deconvolution.
Upgrading from the CSU-W1：CSU-W1 SoRa

Uniformizer

Most suitable option for CSU-W1 illumination uniformity. Uniform and efficient illumination of the entire wide field of view.

Near Infrared (NIR) Port

NIR port provides up to 785nm excitation capability to allow less-invasive deep imaging. The NIR laser is introduced via a dedicated optical fiber in the same way as visible lasers. It is possible to combine NIR and visible lasers within the CSU-W1 unit to allow simultaneous excitation.

External light path

External light path provides the direct path bypassing the disk s to microscope. Versatile applications such as photo activation are available by introducing an external light scanner through this port.

Lens switcher

Newly designed motorized lens switcher between 2 relay lenses i s useful for fitting CSU-W1 image size with various camera types, and also for easy magnification change without exchanging objective lenses.

Variable aperture

Variable aperture to change laser illumination area, and thus the imaging area by the CSU-W1, is useful to minimize laser damages in the specimen.
