Because these instruments all date from the ‘s and ‘s or before, information on them is becoming harder and harder to find. Again, though, for AO Microscopes, what cleaning agent to use shouldn’t be a mystery because recommendations are given by AO in the manuals for your specific scope as found below. Note: Many of these files were furnished to me by Robert Tolley, after I had contributed a Darkfield manual and the newer Series 10 manual, who in-turn, received it from others, so I believe that many amateurs have probably contributed to this collection over the years. I have since tried to add to it as documents or scans have been kindly sent to me, or I have been able to bid on them on eBay. I am searching for an AO Series 2 or Series 4 reference manual, if you have one, please contact me. Also this pdf version contributed by Carl Hunsinger. The version is available right here 2. The version is also available right here 2. The AO Series 10 Catalog 3.

Single-molecule assays have, by definition, the ultimate sensitivity and represent the next frontier in biological analysis and diagnostics.

However, many of these powerful technologies require dedicated laboratories and trained personnel and have therefore remained research tools for specialists. Here, we present a single-molecule confocal system built from a 3D-printed scaffold, resulting in a compact, plug and play device called the AttoBright. This device performs single photon counting and fluorescence correlation spectroscopy FCS in a simple format and is widely applicable to the detection of single fluorophores, proteins, liposomes or bacteria.

A number of scientific instruments now possess single-molecule sensitivity and have enabled the discovery of novel disease biomarkers at extremely low concentrations 1. Recent breakthroughs in single-molecule fluorescence super-resolution imaging have provided exquisite details into many biological processes in living cells 2 , 3 , 4. In vitro, measurements of individual proteins have enabled the direct observation of folding trajectories or aggregation, leading to new understanding of fundamental molecular mechanisms 5.

This scanning electron microscope image of SARS-CoV-2 shows the coronavirus with a backdrop of cells in pink and blue. We are well aware of the frightening toll it is taking. Now we also have a better look at the virus itself. NIAID’s Rocky Mountain Laboratories in Montana used specialized equipment, scanning and transmission electron microscopes, to capture the digitally colorized close-ups. A transmission electron microscope captured this image of the SARS-CoV-2 coronavirus, which has a distinctive crown-like appearance.

The World Health Organization declared the coronavirus outbreak a global emergency at the end of January.

DSX Digital Microscope. DSX series digital microscopes combine the quality of our renowned optical technologies with the ease of use of digital technologies. The DSX digital microscope is used to observe and measure a variety of samples, including electronic components and metal materials. The microscope requires little training to use; simply place your sample and easily perform a series of operations from 3D observation to measurement and reporting. The DSX microscope meets a wide range of observational and analytical needs in a single unit while improving the inspection workflow.

An expanded lineup of 15 lenses covers a ,X magnification range. For example, techniques are available to highlight irregularities on a sample surface or emphasize contours. In addition, newly developed algorithms can be used to acquire 3D images approximately ten times faster than conventional digital microscopes. Five new objective lenses are available for the DSX digital microscope, bringing the total up to The ,X magnification range enables precise observation, while long working distance objectives make it possible to observe irregular samples, such as electronic boards and machined components.

A comparison of wafer images at 20—7,X. Using a high-resolution long working objective lens The long working distance enables users to observe electronic substrates with irregularities. The electric zoom head incorporates advanced observational functions, enabling the use of six observation methods and contrast UP functions: brightfield, darkfield, MIX, polarizing, simple polarizing and differential interference contrast. The polarization observation and contrast UP functions can highlight the irregularities and contours of a sample surface.

The conventional optical microscope has been the primary tool in assisting pathological examinations. The modern digital pathology combines the power of microscopy, electronic detection, and computerized analysis. It enables cellular-, molecular-, and genetic-imaging at high efficiency and accuracy to facilitate clinical screening and diagnosis.

This paper first reviews the fundamental concepts of microscopic imaging and introduces the technical features and associated clinical applications of optical microscopes, electron microscopes, scanning tunnel microscopes, and fluorescence microscopes. The interface of microscopy with digital image acquisition methods is discussed.

Nothing ages as elegantly as an antique microscope. A bridge to an age when craftsmanship was as important as functionality, a vintage microscope is a work of art as well as science. In the late 16th century several Dutch lens makers designed devices that magnified objects, but in Galileo Galilei perfected the first device known as a microscope. His invention, a compound microscope, had a convex and a concave lens.

Later that century, Anton van Leeuwenhoek refined the microscope for biological research. These first fledgling microscopes were generally built and used by a scientist. They can only be found in museums and are not available to the average antique microscope collector. Usually made of brass, the first microscopes were monocular instruments with simple lenses.

The absorption and subsequent re-radiation of light by organic and inorganic specimens is typically the result of well-established physical phenomena described as being either fluorescence or phosphorescence. The emission of light through the fluorescence process is nearly simultaneous with the absorption of the excitation light due to a relatively short time delay between photon absorption and emission, ranging usually less than a microsecond in duration. When emission persists longer after the excitation light has been extinguished, the phenomenon is referred to as phosphorescence.

British scientist Sir George G. Stokes first described fluorescence in and was responsible for coining the term when he observed that the mineral fluorspar emitted red light when it was illuminated by ultraviolet excitation. Stokes noted that fluorescence emission always occurred at a longer wavelength than that of the excitation light. Early investigations in the 19th century showed that many specimens including minerals, crystals, resins, crude drugs, butter, chlorophyll, vitamins, and inorganic compounds fluoresce when irradiated with ultraviolet light.

However, it was not until the s that the use of fluorochromes was initiated in biological investigations to stain tissue components, bacteria, and other pathogens. Several of these stains were highly specific and stimulated the development of the fluorescence microscope.
