The microscope used to view blood cells is called a light microscope, specifically a compound light microscope.

Here's why:

* Light microscope: This type of microscope uses visible light to illuminate the specimen and lenses to magnify the image.

* Compound light microscope: This refers to the use of multiple lenses to achieve higher magnification.

Blood cells are transparent, so they need to be stained to be visible under the light microscope. This staining helps to differentiate the different types of blood cells, like red blood cells, white blood cells, and platelets.

While other types of microscopes exist, like electron microscopes, they are not typically used for viewing blood cells due to their complexity and cost.
