difference between transmitted and reflected light microscope

In a light microscope, we use visible light and in an electron microscope, the beam of electrons is used. After the light passes through the specimen it goes through the objective lens to magnify the image of the sample and then to the oculars, where the enlarged image is viewed. Michael W. Davidson - National High Magnetic Field Laboratory, 1800 East Paul Dirac Dr., The Florida State University, Tallahassee, Florida, 32310. Together, the polarizer and retardation plate comprise the de Snarmont compensator (Figure 5(c)). The light path of the microscope must be correctly set up for each optical method and the components used for image generation. Answer (1 of 4): 1. p[o-0 When the polarizer axis is rotated up to 45 degrees in one direction, right-handed elliptical or circular polarizer light emerges from the de Snarmont compensator. Our Glan-Thompson Calcite Polarizers are designed to meet the most demanding applications that require high purity linear polarization. Image contrast arises from the interaction of plane-polarized light with a birefringent (or doubly-refracting) specimen to produce two individual wave components that are each polarized in mutually perpendicular planes. In brightfield or darkfield illumination, these structures are often observed merged together and can become quite confusing when attempting to image specific surface details.

Transmitted light microscopy is the general term used for any type of microscopy where the light is transmitted from a source on the opposite side of the specimen to the objective lens. The limitations of bright-field microscopy include low contrast for weakly absorbing samples and low resolution due to the blurry appearance of out-of-focus material. When the polarizers remain in place and the Nomarski prism slider is removed, the microscope is configured for observation in polarized reflected light mode.
