What are the Different Types of Microscopes Used in Histology?
Several types of microscopes are used in histology, each with its own resolution limits:
Light Microscopes: These are the most common in histology labs and include bright-field, phase-contrast, and fluorescence microscopes. Their resolution limit is around 200 nanometers. Electron Microscopes: These include transmission electron microscopes (TEM) and scanning electron microscopes (SEM). TEM has a resolution limit of about 0.1 nanometers, while SEM is around 1-2 nanometers. Confocal Microscopes: These provide higher resolution than traditional light microscopes by using a laser to illuminate the specimen, achieving a resolution limit of about 180 nanometers.
