Microscopes

Instead of light, traditional high-resolution electron microscopes use a particle beam of electrons to illuminate a specimen. However, the particle beam also destroys the samples, meaning that electron microscopes can’t be used to image living cells. Electrical engineers at Massachusetts Institute of Technology (MIT) have proposed a new scheme that can overcome this critical limitation by using a quantum mechanical measurement technique that allows electrons to sense objects remotely without ever hitting the imaged objects, thus avoiding damage.

Recent developments in the fight against cancer have promised better ways to both identify and treat the disease. Adding to the ever growing list of advancements is Dave Wilson, a Professor of biomedical engineering at Case Western Reserve University in Cleveland. Frustrated by blurry low resolution optical images of diseased tissues, he has developed a cryo-imaging system which can identify and pinpoint the exact location and number of cancer cells in a particular area while displaying the findings as a detailed three dimensional color cyber model.

Like the wizard from the King Arthur legend, the new MERLIN electron microscope has a few tricks up its sleeve. The new Field Emission Scanning Electron Microscope, more conveniently described as a FESEM, from Carl Zeiss SMT AG is designed to overcome the standard trade-offs between image resolution and the analytical capability.

The world unseen, or barely seen, by the naked eye is full of mystery and surprise. For many professions, however, it's also part of the job. People employed to inspect printed circuit boards or the quality of fabrics, verify fingerprints or investigate counterfeit currency and forensics, research plants or appraise gems – the list goes on – all need to look at their worlds in microscopic detail. Extech Instruments' hand-held digital microscope with camera has just the portability and functionality that makes getting close to their job a whole lot easier. Read More
The CellScope is a revolutionary attachment that turns a standard camera-enabled cell phone into a clinical quality microscope, with magnification up to 50X. Health workers in developing countries, where expensive equipment, facilities and on-the-ground physicians are scarce, will be able to use the mobile microscope to quickly and easily capture images of blood cells, lesions and infections and transmit them via the cell phone network to remote experts for analysis and diagnosis.

A simple to use tool for capturing the fine detail of almost any object from coins, plants and rocks to electronic circuit boards, Celestron's new handheld USB digital microscope provides 10x to 40x and 150x magnification and a 1.3mp digital camera for capturing stills and video. Read More
Microscopes have been an integral tool for scientists for hundreds of years, opening up the world that surrounds us and providing countless scientific breakthroughs. Now the most advanced and powerful electron microscope on the planet—capable of unprecedented resolution—has been installed in the new Canadian Centre for Electron Microscopy at McMaster University in Ontario.

Carl Zeiss SMT has introduced an improved version of its helium ion microscope at the Microscopy and Microanalysis 2008 exhibition: the ORION PLUS. By focusing helium ions into a beam, instead of electrons, the microscope can offer higher focus with lower sample damage. Read More
June 24, 2008 In order to view cells at a high enough magnification to identify cancerous and pre-cancerous growths, doctors currently have to perform biopsy surgery - the invasive removal of cells so they can be examined in a laboratory. But a new Australian endoscope technology is about to remove the need for a biopsy altogether by offering doctors the ability to examine tissue at single-cell and sub-cellular magnification levels as the camera moves through the body. Optiscan's miniature endomicroscope offers up to 1000x magnification as opposed to the 40x magnification of traditional endoscopes, and will greatly speed up the detection and diagnosis of cancerous cells.
