Principles of Spinning disk confocal

The most common conventional confocal microscopes use a single laser beam to scan a specimen, while the CSU scans the field of view with approximately 1,000 laser beams, by using microlens-enhanced Nipkow-disk scanning: in short, CSU can scan 1,000 times faster.

By using a disk containing microlens arrays in combination with the Nipkow disk, we have succeeded in dramatically improving the light efficiency and thus successfully made real-time confocal imaging of live cells possible.

The expanded and collimated laser beam illuminates the upper disk containing about 20,000 microlenses (microlens array disk). Each microlens focuses the laser beam onto its corresponding pinhole, thus, effectively increasing laser intensity through pinholes placed in the pinhole array disk (Nipkow disk).

With the microlens, backscattering of laser light at the surface of the pinhole disk can be significantly reduced, thus, dramatically increasing the signal to noise ratio (S/N) of confocal images.

About 1,000 laser beams passing through each of the pinholes fill the aperture of the objective lens, and are then focused on the focal plane. Fluorescence generated from the specimen is captured by the objective lens and focused back onto the pinhole disk, transmitted through the same holes to eliminate out-of-focus signals, deflected by the dichroic mirror located between microlens array disk and the Nipkow disk to split fluorescence signal from reflected laser, passed through emission filter and then focused into the image plane in the eyepiece or camera.

The microlens array disk and the Nipkow disk are physically fixed to each other and are rotated to scan the entire field of view at high speeds, thus, making it possible to view confocal fluorescent images in real-time through the eyepiece of the CSU head.

As compared to conventional single point scanning, multi beam scanning by the CSU requires a significantly low level of light intensity per unit area, which results in significantly reduced photo bleaching and phototoxicity in live cells.

Discovering Potential Covid-19 Therapies using High Content Screening

Date: Wednesday August 26th 2020
Time: 12pm (EST) 9am (PST) 5pm (London)

In this webinar, Professor Jonny Sexton discusses a pipeline, developed in the Sexton lab, for the quantitative high-throughput image-based screening of SARS-CoV-2 infection to identify potential antiviral mechanisms and allow selection of appropriate drug combinations to treat COVID-19. This webinar presents evidence that morphological profiling can robustly identify new potential therapeutics against SARS-CoV-2 infection as well as drugs that potentially worsen COVID-19 outcomes.
