Revolutionize Your Confocal Imaging with ZEISS Airyscan

Airyscan is an array detector that draws on the fact that a fluorescence microscope will image a point-like source as an extended airy disk. When you close the pinhole in a standard confocal microscope to reject out-of-focus light, you get a sharper image, but it’s also dimmer since a great deal of light is then lost. The smaller the pinhole, the higher the resolution, but – equally – the bigger the loss in light.

Airyscan solves this conundrum between resolution and light efficiency by imaging the complete airy disk onto a concentrically arranged hexagonal detector array. It consists of 32 single detector elements, all of which act like sub airy unit pinholes. The confocal pinhole itself remains open and doesn’t block light – thus all photons of the whole airy disk are collected.

The signals from all detector elements are then reassigned to their correct position, producing an image with increased signal-to-noise ratio and resolution. Unlike other superresolution techniques, Airyscan capitalizes on the scanning and optical sectioning capabilities of a confocal. Thus Airyscan even works with thicker samples such as tissue sections or whole animal mounts that need a higher penetration depth.

Beam Path

A Streamlined Light Path with Surprising Flexibility

The compact light path of LSM 800 with Airyscan is designed for highest efficiency, with a minimum of optical elements for highest sensitivity. Fluorescence emission light travels through the main dichroic beam splitter with its outstanding laser suppression to deliver supreme contrast.

Up to two patented variable beam splitter dichroics (VSDs) divert the respective spectral parts of the fluorescence emission light. You can freely define up to three detectors: multialkali, GaAsP or Airyscan.

Fast and Linear Scanning

Your Powerful Combination

LSM 800 gives you the benefit of increased scanning speeds so you can resolve those fast movements of labeled proteins that demand equally fast scanning. At an image size of 512 × 512 pixels you will be capturing events with up to 8 frames per second.

Your LSM 800 is constantly monitoring and calibrating the scanner position so you can count on a stable and even field of view with constant pixel times across the whole observation area. This patented linear scanning regime gives you a constant signal-to-noise level and uniform exposure by the illuminating laser throughout the scanned area, including your manipulated regions of interest.

With LSM 800 you will be using more than 80% of the scanning time for data acquisition. Signal-to noise improves by about 29% compared to sine scanning systems. Your experiments will always deliver quantitative data. Likewise, you can adapt the scan field at any time by panning or cropping it, and rotating it freely to best suit the geometry of your sample.
