Digital Compound Microscope

• Concepts in Digital Imaging Technology
  This article refers to the charged-coupled devices or CCDs which is an essential part in a digital camera. Attention to its discussion would greatly benefit the interested reader. Charge-coupled devices (CCDs), like microprocessor and memory integrated circuits, are fabricated on silicon wafers in a series of elaborate steps using photolithography to define and build various functional elements within the microcircuitry. Each wafer contains tens to hundreds of identical devices, each fully capable of producing a single CCD chip for use in digital cameras. This section of the Molecular Expressions Photomicrography Primer contains links to illustrated discussions of important CCD concepts, which are critical in forming a complete understanding of digital imaging techniques. read more...


• Introduction to CMOS Image Sensors
  This article refers to two important devices in optical microscopy, but more of the discussions center around the complementary metal oxide semiconductor image sensors or CMOS, its history and development. The arrival of high-resolution solid state imaging devices, primarily charge-coupled devices (CCDs) and complementary metal oxide semiconductor (CMOS) image sensors, has heralded a new era for optical microscopy that threatens to eclipse traditional image recording technology, such as film, video tubes, and photomultipliers. Charge-coupled device camera systems designed specifically for microscopy applications are offered by numerous original equipment and aftermarket manufacturers, and CMOS imaging sensors are now becoming available for a few microscopes. Both technologies were developed between the early and late 1970s, but CMOS sensors had unacceptable performance and were generally overlooked or considered just a curiosity until the early 1990s. read more...


• An Introduction to Computer Image Processing and Analysis
  This article is a continuation of digitization of images from the microscope into the video camera. Why should microscopists (or any other scientist) care about or use computer-based image processing and measurement? There are several reasons; a few are: to assist the human viewer in observing or communicating information in images; to minimize human bias based on wish or expectation; to introduce rigor into the process of obtaining quantitative information as a substitute for anecdote; and not least, to make us better and more aware viewers of images. Unassisted human vision is rarely a reliable scientific tool. Henry David Thoreau said “The question is not what you look at, but what you see.” read more...


• Compound Optical Microscope
  In studying about microscopes, it is imperative for the student to have a thorough knowledge about the terms used, like compound light microscope. How these words came about? The term compound refers to the microscope having more than one lens, whereas simple microscope like the one used by Leeuwenhoek had only one lens. The term light refers to the method by which light transmit the image to the eyes. Micro as we all know refers to small and scope means view. Early microscopes, like Leeuwenhoek’s, were called simple because they only had one lens. Simple scopes work like magnifying glasses that you have seen and/or used. These early microscopes had limitations to the amount of magnification no matter how they were constructed. The creation of the compound microscope by the Janssens helped to advance the field of microbiology light years ahead of where it had been only just a few years earlier. The Janssens added a second lens to magnify the image of the primary (or first) lens. read more...

• Science Research Microscopy
  There are science experts who study and substantiate art objects as well as historical and archaeological relics. These science experts works with devices like spectroscopy, polarized-light microscopy, spectrometry, carbon dating, chromatography, and thermoluminescence in order to find out the origin and history of objects that come into their science laboratory. Microscopy using various microscopes such... read more...


• Food Examination
  If there is a basis to allege that a food has initiated the food poisoning or has endured microbial spoilage, the original product or a low serial dilution of it must be utilized in order to prepare a microscope slide for direct microscopic investigation under a microscope such as the digital compound microscope. The Gram.... read more...


• The Cryptosporidiosis Contamination
  An individual can reduce the probabilities of getting contaminated with Cryptosporidium and various other pathogens by at all times practicing good hygiene, particularly after possible exposure to sources of contamination. Such pathogens can only be detected through microscopy under a microscope like the digital compound microscope. Individuals with compromised immune systems should steadily take precautions... read more...


• Cryptosporidiosis: An Illness from Water
  There are lots of well-documented epidemics of cryptosporidiosis. Majority of these frequently waterborne epidemics have included slight problems in the flocculation and or filtration procedure. These epidemics have injured thousands of people. Some of the immunocompromised patients have died and lots of formerly healthy individuals turned ill. Further epidemics linking the public swimming pools and... read more...


• Anemia
  The commonest reason of anemia is lack of iron. Iron is required to produce hemoglobin. Iron is generally accumulated in the body in the hemoglobin. The latter can be observed clearly through microscopy using a microscope such as digital compound microscope. Approximately thirty percent of iron is also kept as ferritin and hemosiderin in the... read more...
