World's fastest ever confocal microscope
claimed
Carl Zeiss has launched what is said to be the world's fastest ever confocal microscope for live cell research, the LSM 5 live ia said to image 20 times faster than any other confocal microscope.
Carl Zeiss has launched a dedicated live cell imaging system capable of collecting up to 120 full frame images per second, 20 times faster than any other confocal system Called LSM 5 live, the new system delivers faster, brighter, more evenly illuminated and better contrasted images than ever before and underlines the company's technological leadership in fluorescence microscopy

Confocal laser scanning microscopes
The LSM 5 DUO combines two award-winning confocal laser scanning microscopes, the LSM 510 META and LSM 5 LIVE, to form a single state-of-the-art instrument.
Optical Height Measurement In The Nanometer Range
Carl Zeiss has developed a quick, simple and economic solution for the precise measurement of surface topography, roughness and layer thickness such as in the fields of films and coatings.
The pinnacle of the award-wining LSM 5 family, the new instrument's unique combination of high speed, image quality and sensitivity will provide exclusive insights into the cell's highly transient and dynamic events.
It is ideally suited to studies at the forefront of live cell imaging, such as the movement of individual intracellular molecules or measuring the dynamics of the cytoskeleton during such processes as cell adhesion, cell motility and cell signalling.
Until now, these ultra-fast processes have been at or beyond the limits of microscopical systems but the LSM 5 live captures events of the order of microseconds.

Carl Zeiss has brought out two highly sensitive digital cameras specially designed for photomicrography in biomedical research.
High Speed High Resolution Cost Effective Imaging
With a dynamic range of 1:1300, the MRc5 high-resolution 5 megapixel digital camera with FireWire, produces colour images of exceptional accuracy, brilliance and needle sharp detail.
"The combination of high resolution, sensitivity and speed is essential to track the communication and interaction of cells, organisms and structures," says Aubrey Lambert, Carl Zeiss UK.
"LSM 5 live now makes that possible.
Unlike any other fast-scanning technology, the live system does not sacrifice excitation or emission efficiency and delivers outstanding image quality and exceptional sensitivity and opens up a new time window for confocal microscopy.
The speed, resolving power and sensitivity of the LSM 5 live are driven by a completely new optical concept specially tailored for studies on living specimens.
Totally different to any other system, the light beam is shaped into laser light of rectangular cross section and focused precisely on the groundbreaking colour-independent AchroGate beam splitter.
This guarantees virtually 100% excitation efficiency and emission yield at all wavelengths to deliver maximum performance even on thick or weakly fluorescent specimens, common problems in live cell imaging.
An ultra-fast CCD line detector picks up the shaped laser light to allow parallel imaging of 512 pixels with high quantum yield.
It will capture up to 120 confocal images per second at a resolution of 512 x 512 pixels and can attain 505 or 1,010 frames per second at reduced formats of 512 x 100 pixels or 512 x 50 pixels.
This is combined with zoom optics and an ultrafast Z-drive that permit 3D image stacks to be acquired every second, especially useful for developmental biologists.
The LSM 5 live confocal microscope launches alongside two other groundbreaking fluorescence microscope systems.
The Axio Imager is an innovative modular system for digital fluorescence microscopy, featuring IC2S objectives (Infinity Contrast and Colour Corrected System) that optimise image quality and maximise contrast in all techniques and special fluorescence filters that permit excitation intensity up to 70% higher than normal microscopes to reduce exposure times by up to 50%.
Meanwhile, the SteREO Lumar.V12 builds on Carl Zeisss reputation as the inventors of stereomicroscopy to offer a fully-fledged fluorescence imaging system providing 20% more image information with integrated microscope control, image recording, processing, analysis, administration and archiving.
