what kind of lenses is shown on the micrsope to the righty?

To determine the type of lenses shown on a microscope, you would typically need a visual reference or description of the microscope in question. Without a visual or specific description, it is difficult to determine the exact type of lenses. However, most microscopes consist of multiple lenses including an objective lens (located near the specimen) and an eyepiece lens (located near the viewer's eye). These two lenses work together to magnify and focus the image. Additionally, some microscopes may also have additional lenses such as condenser lenses or specialized objective lenses for different magnification levels or imaging techniques. A visual inspection or specific details about the microscope's lenses would be helpful in determining their type.
