Parts of the Bright Field … Bright-field microscopy (BF) is the simplest of all the optical microscopy illumination techniques. Sample illumination is transmitted (i.e., illuminated from below and observed from above) white light, and contrast in the sample is caused by attenuation of the transmitted light in dense areas of the sample. Bright-field … See more The light path of a bright-field microscope is extremely simple, no additional components are required beyond the normal light-microscope setup. The light path therefore consists of: • a … See more Bright-field microscopy typically has low contrast with most biological samples, as few absorb light to a great extent. Staining is often required to increase contrast, which prevents use on live cells in many situations. Bright-field illumination is useful for samples that … See more

To be seen in bright field, the microscopic specimen must introduce one or both of these into the uniform illuminating beam. Differential absorption and differential refraction produce contrast in bright field microscopy. Specimens that have color of their own or which can be stained are appropriate for bright field.

WebBright Field Microscopy. With a conventional bright field microscope, light from an incandescent source is aimed toward a lens beneath the stage called the condenser, through the specimen, through an objective lens, and to the eye through a second magnifying lens, the ocular or eyepiece. Most microscopes will have a built-in illuminator.
