• Fundamentals of Differential Interference Contrast Microscopy
  Here is an article about the fundamentals of differential interference microscopy, and its configuration by the Olympus Microscopy Resource Center. In the mid-1950s, a French optics theoretician named Georges Nomarski modified the Wollaston prism used for detecting optical gradients in specimens and converting them into intensity differences. Several implementations of this design, which is called differential interference contrast. read more...


• Mastering Simple Bacterium Examination Techniques Using Phase Contrast Microscopy
  Experts universally agree that bacterium examination techniques using phase contrast microscopy yield the best results. They may not be perfect, but they definitely deliver better and more detailed images. Studying bacteria is considered vital because it allows scientists to learn more about the origins of diseases and consequently determine cures for them as well. Bacterial Observation: Problems and Methods Bacteria have been in existence for billions of years already. Due to their size and near transparency, bacteria are impossible to observe with the naked eye. Even an ordinary microscope isn’t much help. Thankfully, various techniques have been discovered over the years to improve the study of bacteria.read more...

• Proper Use of the Phase Contrast Microscope
  Biological tissues can be examined using a phase contrast microscope. This is a type of microscope that uses light to enhance contrasts of colorless and transparent objects. This microscope enables components to be shown in bacteria or cells that are very difficult to see when you use an ordinary microscope. Meaning, the very invisible component of bacteria can be seen if you are going to use the phase contrast microscope. However, the objective lenses used here and the phase contrast condensers are very costly, that is why the phase contrast microscope is rarely used in teaching labs, unless the classes are mainly for health professions. The phase contrast microscope is composed of four objective lenses, a phase condenser lens and lastly a centering telescope.read more...


• Accessories for Phase Contrast Microscopes
  Phase contrast microscopes are optical microscopy instruments that provide high contrast images with the use of optical techniques. Unlike the more conventional types of microscopes, phase contrast microscopes are capable of detecting extremely tiny variations in a specimen’s phase and translate these corresponding amplitude changes. This results to a high-contrast image of the specimen, offering better visuals for examination and evaluation. Phase contrast microscopes can be used with living cells, so cells may be viewed without killing or processing them with the use of staining medium or fluorescence. Any changes in the biological processes of these cells may be observed in great detail. read more...


• New Phase-Contrast Microscopy Developed at PSI Enhances X-ray Images
  Ever wonder what you’ll do without the luxury of technology? The Paul Scherrer Institute or PSI is a company that deals with development of imaging techniques that are so important in our tech toys. However, these are not only used in our technological devices but are also vital in the development of machines that aid in medical sciences and research. Applications in disease conditions like Alzheimer’s disease or osteoporosis are also being helped with advanced technologies. As a whole, the society benefits as our technologies get better. read more...


• Phase Contrast Illumination
  Gregor T. Overney writes about his experiences with phase contrast microscopes in this article. He supplements his text with informative pictures and images that help the reader understand and make comparisons. He touches a little on the history of phase contrast microscopes. He pays tribute to the man who first described the method in 1934, a Dutch physicist called Frits Zernike. This invention was so highly regarded and paved the way for so many discoveries that Zernike was awarded a Nobel Prize for it. Phase contrast microscopes allow for the clear and detailed visualization of otherwise invisible microorganisms in their own habitat. When compared to bright field microscopy, which requires the specimens to be stained, often killing and immobilizing them. With phase contrast microscopy, living cells can be observed directly without any preparation at all. read more...


• Principles of Phase Contrast Microscopy
  Phase contrast microscopes and everything you need to know about them are discussed in this article. It compares the differences between bright field microscopy and phase contrast microscopy. The text also includes common words and terms that will help you familiarize yourself with its uses, principles and limitation, if any. Phase contrast microscopes allow for the visualization of specimens that are usually in a liquid sample, to be viewed clearly. One of the great advantages of this method as compared to bright field microscopy is that the specimens do not need to be stained or prepared in any way before it can be viewed. Very small and almost invisible microorganisms are also clearly distinguished, as it is very difficult to do in bright field microscopy. read more...


• Hotshot Genius Tools: What You Should Know about Phase Contrast Microscopes
