What kind of microscope would be used to study a whole or opaque object?

To study a whole or opaque object, a stereomicroscope (also known as a dissecting microscope) is typically used. This type of microscope provides a three-dimensional view and allows for the examination of the surface features of the object at low magnification. It uses reflected light to illuminate the specimen, making it suitable for larger or opaque samples that cannot be viewed with traditional compound microscopes.
