ZEISS LSM 800 with Airyscan

Your Compact Confocal for High-End Imaging

Confocal imaging demands the very best imaging quality. With LSM 800 you choose a flexible and compact confocal laser scanning microscope, complete with highly sensitive GaAsP detection and fast linear scanning. Add Airyscan, the revolutionary detection concept from ZEISS to acquire perfect optical sections with a resolution of 120 nm (in x,y) and 350 nm (in z) even in thick samples. With the 4 – 8× better signal-to-noise ratio (SNR) of Airyscan you will be pushing sensitivity and superresolution imaging beyond the limits of all conventional confocals.

LSM 800 is your entry into the world of high-end confocal imaging. Simply decide which options your system needs today, then upgrade in the future as your needs grow.

Revolutionize Your Confocal Imaging with ZEISS Airyscan

Airyscan is a detector that draws on the fact that a fluorescence microscope will image a point-like source as an extended Airy disk (Airy pattern). In a standard confocal microscope the out-of-focus emission light is rejected at a pinhole, the size of which determines how much of the Airy pattern reaches the detector.
When you increasingly close the pinhole 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 greater the loss in light. Airyscan solves this conundrum between resolution and light efficiency by imaging the Airy disk onto a concentrically-arranged hexagonal detector array. Its detection area consists of 32 single detector elements, each of which acts like a very small pinhole.

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.

An area detector consisting of multiple detector elements allows great flexibility in imaging modes. Instead of closing the pinhole and universally blocking light, each photon from the z-section is kept. The additional information about the Airy pattern gives access to a perfect optical section with highest sensitivity. Airyscan works with your standard samples and dyes. It's your choice, whether you use it to get better SNR, superresolution or speed.

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.

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.
