Web16 mrt. 2024 · Phase contrast is a technique for optical microscopy which is used to enhance the contrast of unstained specimens. Structures of unstained specimens, such as living cells or their organelles, can appear obscure and transparent when viewed with brightfield illumination. Web9 jun. 2011 · Brightfield microscopy often only provides a weak image of unstained specimens, in which only a few details are detectable. A stronger contrast is important to see more details in the picture. One way to enhance contrast is to stain the sample.
