WebBrightfield imaging or transmitted light microscopy usually has very low contrast between signal and background, therefore there are a number of techniques available which will … WebPhase Contrast vs. Bright Field Microscopy. An amplitude specimen decreases the intensity (i.e. the amplitude) of the light. Phase specimens cause a phase shift of the light. This phase shift can not be detected with the unaided eye and requires a phase contrast microscope. Air is completely transparent, I hope you agree. And water is transparent.
