Phase Plate

A phase plate is a device used in microscopy and imaging systems to enhance contrast by altering the phase of light passing through a sample. When light interacts with a specimen, it can change in ways that are hard to see directly. The phase plate introduces a specific change in the light’s wave pattern, making subtle differences more visible without damaging the sample. This results in clearer, more detailed images, especially useful for observing transparent or delicate structures that would otherwise be difficult to distinguish with standard microscopy techniques.
