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 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. The TC-5300 Series inverted biological microscopes have been designed to be versatile, modular, ergonomic, system ideal for use in research, educational and clinic applications. The TC-5300 are well suited for wide variety of routine examination of tissue culture, precipitates and high resolution video microscopy. The TC-5300 Series microscopes deliver crisp, distortion-free, high resolution images in multiple modes of operation.
