This year the Nobel Prize for chemistry was awarded to three researchers who laid groundwork to a now-booming field of super-resolution fluorescent microscopy. WE Moerner, Eric Betzig and Stefan Hell have worked on novel ways of using classical fluorescent microscopy to tackle the Abbe diffraction limit of optical resolution, which defines what we can resolve with a light microscope.

The Abbe limit means that it is not possible to glimpse at objects closer to one another than approximately 200 nm or two hundred billionths of a meter. However, the vast majority of cellular events happening on the molecular level take place at distances of tens of nanometers and below which is 10-to-100-fold smaller than what a light microscope can resolve. The three Nobel laureates have looked into addressing this challenge since the1990s and it became increasingly plausible that the Abbe limit may eventually be circumvented. This was achieved by the combination of the developments in fluorescent labeling, rapid and sensitive imagers (primarily EMCCD sensors) as well as modification of existing optical microscopes and laser systems

Fast imaging cameras were instrumental in several super-resolution experiments and allowed the researchers to collect the hundreds of thousands of images often needed to create one set of super-resolved images of cells' interiors. Andor Technology has long been involved in collaboration with all three researchers at the forefront of topics related to optimization of imaging cameras deployed for super-resolution microscopy. All three Nobel prize winners used Andor EMCCD cameras in their super-resolution research and the collaboration between them and Andor resulted in faster, lower-noise, single photon-sensitive scientific cameras that became the imagers of choice for the majority of researchers in this field.

Thanks to the combined work of WE Moerner, Eric Betzig and Stefan Hell we are now able to obtain insights into intracellular structures like cytoskeleton, vesicles (transport organelles) and mitochondria (cell's power plants) at an unprecedented sharpness, contrast and clarity. This Nobel prize crowns a body of work that is just the beginning and may open new research fields leading to significant progress in nanotechnology, biotechnology and molecular medicine by allowing access to what Richard Feynman famously alluded to as "plenty room at the bottom" in his 1959 nanotechnology lecture.

iXon Ultra 888 EMCCD Camera

Oxford Instruments Andor

The highly innovative iXon Ultra 888 is the world’s fastest Megapixel, Back-illuminated EMCCD camera, offering exceptional frame rates and single photon sensitivity across a large field of view. Building on a rich history of first to market innovation, the ‘supercharged’ iXon Ultra 888, represents a massive performance boost for the largest available EMCCD sensor, as well as the first USB3 enabled EMCCD camera. The iXon Ultra 888 has been fundamentally re-engineered to facilitate 3x overclocking of the pixel readout speed to an unprecedented 30 MHz, whilst maintaining quantitative stability, accelerating the full frame rate performance to video rate. Furthermore, Andor’s unique ‘Crop Mode’ can be employed to further boost frame rates from a user defined sub-region, for example pushing a 512 x 512 sub-array to 93 fps and a 128 x 128 area to 697 fps. With a 1024 x 1024 sensor format and 13 µm pixel size, the resolving power, field of view and unparalleled speed of the iXon Ultra 888 render it the most attractive and versatile EMCCD option for demanding applications such as single molecule detection, super-resolution microscopy, live cell imaging and high time resolution astronomy.Features: 30 MHz readout delivering 26 fps at 1024 x 1024 > 2.6x larger Field of View than ‘897’ model Optically Centered Crop Mode – Live Cell Super Resolution at 697fps Single Photon Sensitive EX2 Technology for wider QE response TE Cooling to -95°C

iXon Ultra 897 EMCCD Camera

Oxford Instruments Andor

Facilitated by a fundamental redesign, the NEW iXon Ultra platform takes the popular back-illuminated 512 x 512 frame transfer sensor and overclocks readout to 17 MHz, pushing speed performance to an outstanding 56 fps (full frame), whilst maintaining quantitative stability throughout. The status of ‘Ultimate Sensitivity’ is also preserved in this model, offering thermoelectric cooling down to -100°C and industry-lowest clock induced charge noise. Additional unique features of the iXon Ultra include USB connectivity and direct raw data access for on the fly processing. EMCCD and conventional CCD readout modes provide heightened application flexibility, with a new ‘low and slow’ noise performance in CCD mode.

Newton EMCCD Detector

Oxford Instruments Andor

Both the Andor NewtonEM EMCCD and Newton conventional CCD detector systems have been optimized for high performance spectroscopic applications.   All Newton detector systems employ low noise electronics, cooling to -100°C, up to 95% peak Quantum Efficiency (QE), multi-MHz readout, USB 2.0 connectivity and versatile readout modes. The NewtonEM employs Andor's electron multiplying CCD technology in an exclusive sensor format optimized for ultra-low light, level spectroscopy applications. The combination of the Newton's low noise electronics, high QE, fast readout, and the on-chip amplication (electron multiplication) makes this detector unbeatable for the most demanding ultra-low light level spectroscopy applications, including single photon light level spectra. Dual output amplifiers also allow the detector system to operate in both the electron-multiplication mode and the conventional low noise readout modes, making the detector even more versatile for a wider variety of applications. The Newton series of conventional CCD detectors employ industry leading low noise CCD sensors such as the 2048 x 512 and the 1024 x 256 pixel formats optimized for spectroscopy along with the standard features of ultra low noise electronics, deep cooling, high QE, multi-MHz readout, and USB 2.0 connectivity. The Newton CCD detector also provides dual output amplifiers for user selection of high sensitivity or high capacity operating modes. High performance, and extreme versatility make this the ideal CCD detector to use with Andor's line of Shamrock imaging spectrographs to form a very powerful spectroscopy measurement system for use in even the most demanding applications.
