Several types of lighting are employed in histology, each with its specific applications:
Brightfield illumination: The most common type of lighting, used for general tissue examination. Darkfield illumination: Enhances contrast in unstained samples, useful for visualizing live cells and certain bacteria. Phase-contrast illumination: Used to view transparent specimens by enhancing contrast without staining. Fluorescence illumination: Utilizes fluorescent dyes to study specific structures and proteins within cells.
