Carl Zeiss Microscopy has released LSM 880 with Airyscan. The confocal laser scanning microscope enables fast and high sensitivity super-resolution microscopy in x, y and z, and high image-acquisition speed in one system.


With the new confocal technology, users achieve a 1.7x higher resolution in all spatial dimensions, 140 nm laterally and 400 nm axially. The improved sensitivity leads to better image quality and increased speed. The whole imaging process is possible with standard sample preparation and labeling protocols.


Technology Background of Airyscan
A classic confocal microscope illuminates one spot on the sample to detect the emitted fluorescence signal. Out-of-focus emission light is rejected at a pinhole, the size of which determines how much of the Airy disk reaches the detector. Users can increase the resolution by making the pinhole smaller, but the signal-to-noise ratio drops significantly, since less valuable emission light is passing through. With Airyscan, Zeiss introduces a new concept. Instead of detecting signals with a single point detector, a multichannel area detector with 32 elements collects all the light from an Airy disk simultaneously. Hereby, each detector element functions as a single, very small pinhole. Knowing the beam path and the spatial distribution of each Airy disk enables very light-efficient imaging: researchers can now use all of the photons that the objective collected.
