The simplest of all the optical microscopy illumination techniques. Sample illumination is incident (i.e. illumination from above and observed from above) or transmitted (i.e., illuminated from below and observed from above) white light and contrast in the sample is caused by absorbance of some of the transmitted light in dense areas of the sample. Brightfield microscopy is the simplest of a range of techniques used for illumination of samples in light microscopes and its simplicity makes it a popular technique. The typical appearance of a brightfield microscopy image is a dark sample on a bright background.Polarizing Light. A type of optical microscopy techniques involving polarized light. Simple techniques include illumination of the sample with polarized light. Directly transmitted light can, optionally, be blocked with a polarizer orientated at 90 degrees to the illumination. More complex microscopy techniques which take advantage of polarized light include differential interference contrast microscopy and interference reflection microscopy.The MT9430 Series Incident and Transmitted Polarizing Microscope is an investigative tool for isotropic and anistropic materials. This series is the most suited in generating interference figures and in mineralogy in the scientific study of crystal structure and physical (including optical) properties of minerals. Specific studies include process of mineral origin and formation, classification of minerals, their geographic distribution as well as their utilization. Ergonomic placement of controls allows for stress free operation, increased lab efficiency and maximum productivity. Our redesigned polarizing condensers enhance performance in polarized light, yielding unmatched image contrast, provide exceptionally bright, crisp images with good color rendition and superior flat fields of view. A perfect instrument for geology, petrology, mineralogy, forensics, material science, manufacturing, crystallography, medical research, environmental science and industrial quality control and quality assurance applications.
