LSM 880 Laser Scanning Confocal Microscope with AiryScan
This new state-of-the art, fast scanning (27 frames/sec @ 480 x 480 pixels) near super-resolution confocal microscope (max 140nm lateral and 400nm axial resolution) was installed in September 2016.
It comprises an inverted, fully motorised (X,Y,Z) Zeiss Axio Imager 2 with 10x, 20x, 40x and 63x objectives, which supports epifluorescence (RGB) and brightfield microscopy. The stand is equipped with an incubation system with temperature and CO2 control making it possible to image living material in addition to fixed, sectioned biological material.
The system is equipped with a Diode 405nm laser, a Multiline Argon laser (wavelengths 458nm, 488nm and 514nm), a DPSS 561nm laser, a HeNe 594nm laser and a HeNe 633nm laser. The confocal has a range of ultra-sensitive detectors, including the Airyscan detector module, that are run through the user-friendly ZEN software platform. The software includes modules for 3D/4D reconstruction and animation; spectral scanning; analysis and quantification of co-localisation; spectral unmixing, advanced tiling and photo-bleaching (FRAP, FRET).
This core confocal microscope facility was made possible by a grant from Barts Charity.

Leica TCS SP5 & TCS SP8 up-right Laser Scanning Confocal Microscopes (up-right)
These 2 systems have upright configurations designed for intravital microscopy (VM) but are also able to cater for fast and highly sensitive multi-colour confocal imaging of fixed preparations such as whole-mounted tissues or cell culture samples. Both systems are laser point-scanning devices and will support 4D imaging applications. Both microscopes are configured to scan in two different modes:
1. Standard mode for higher resolution with speed of scanning between 400Hz to 1800Hz.
2. Rapid – Resonancemode for fast acquisition with a speed of scanning of 8000Hz (e.g. ~ 50 frames for 30 sec at a resolution of 1024 x1024 with 3 colours).
Leica systems use a prism/slit technology (e.g. adjustable band-pass filters) to finely tune the recovered wavelengths to your needs.
