DEMO: Nikon SIM-TIRF, October 4th-20th 2021

The Bioimaging Facility at IST Austria is hosting a demonstration of a Nikon N-SIM system from October 4th – 20th, 2021.

The N-SIM S Super Resolution Microscope is a unique high-speed structured illumination system that achieves acquisition speeds of up to 15 fps, enabling fast biological processes to be captured at twice the spatial resolution of conventional light microscopes (up to 115nm in XY). Combining the N-SIM S and a confocal microscope gives you the flexibility to select a location in the confocal image and switch to super-resolution to view the desired part of the location in minute detail.

Demo-test sessions:

We offer morning and afternoon slots starting from October 4th to 8th (week 1), October 11th to 15th (week 2) and from October 18th to 20th (week 3). The N-SIM system  will stay at IST until the 20th of October in our room in the multi-purpose hall. We will have a super resolution application specialist from Nikon on site from October 4th to October 8th, 2021. In the second Demo week from 11th to 15th of October 2021, the system will be operated by BIF members. External scientists are welcome to try the system.
