Zeiss Lightsheet Z.1

Lighsheet microscopy is a fluorescence-based imaging technique that is growing in popularity. It outperforms other techniques in its ability to rapidly capture large optically sectioned three dimensional datasets, whilst keeping photo-toxicity and bleaching to a minimum. It therefore lends itself well to imaging samples larger than those typically attempted by conventional fluorescence microscopy such as tissues, whole organs and even embryo development. 

Zeiss LSM 780

The Zeiss LSM 780 is a high-sensitivity laser scanning confocal microscope. Unlike most standard confocal systems this instrument comes equipped with a GaAsP photodetector. This detector in addition to boasting a quantum efficiency of 45% (in comparison to 25% for standard PMTs), it can also be used as a single-point detector or as a 32-channel detector array facilitating spectral measurements. It can also be switched into a single-photon counting mode providing great signal to noise for such techniques as FCS and RICS. 

Zeiss LSM 800

The Zeiss LSM 800 is an inverted Zeiss Axio Observer Z1 laser scanning confocal microscope equipped with high quantum efficiency GaAsP detector, 2 multi-alkali PMTs and DIC optics for trans-illumination microscopy with each objective. In addition, the Airyscan module can deliver images with 1.7 x improved resolution (120 nm in x / y and 350 nm in z) and 4-8 x better signal-to-noise ratio, with fast linear scanning. Airyscan works with thicker samples such as fixed tissue sections or whole animal mounts that need a higher penetration depth.

Zeiss LSM 880

The Zeiss LSM 880 is an inverted laser scanning confocal microscope equipped with high quantum efficiency GaAsP detector and 2 multialkali PMTs, which can be used as single point detectors or combined for 34 channel spectral imaging. In addition, the Airyscan module can deliver images with 1.7 x improved resolution (140nm axially, 400 nm laterally) and 4-8 x greater signal-to-noise ratio, at the highest speed of any linear scanning confocal system. BiG.2 Type A (2x GaAsP detectors) non-descanned detectors for the multi-photon laser can be used for imaging thick specimens, with deeper penetration and decreased phototoxicity compared to single photon lasers. The Picoquant system utilises the multi-photon laser to perform Fluorescence Lifetime Imaging (FLIM), Fluorescence Correlation Spectroscopy (FCS), Forster Resonance Energy Transfer (FRET). The Zeiss 880 is also equipped with polarisers for anisotropy measurements.
