WebThe bright-field technique requires a strong light source for high magnification. This can produce heat and damage specimens, and can even kill living microorganisms. Enhancements Fortunately, many of these limitations can be altered, or fixed entirely, by adjusting the microscope’s equipment. WebThe objectives are mounted on a nosepiece under the stage with their front lenses facing upward towards the specimen and focusing is accomplished either by moving the …
WebPhase-contrast microscopy (PCM) is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image. Phase shifts themselves are invisible, but become visible when shown as brightness variations. When light waves travel through a medium other than a vacuum, interaction …
