A microscope that provides a right-side-up image is called a "simple microscope" or a "single-lens microscope." This type of microscope consists of a single convex lens and does not invert the image. When you look through a simple microscope, the image appears in the same orientation as the object being observed. However, it's important to note that simple microscopes have limited magnification capabilities compared to compound microscopes, which use multiple lenses and can achieve higher magnification.
A compound microscope is a type of microscope that provides a right-side-up and inverted image. It consists of multiple lenses, typically an objective lens and an eyepiece lens, which work together to magnify the specimen being observed.
In a compound microscope, the objective lens is located near the specimen and produces an inverted image of the specimen. This image is then magnified further by the eyepiece lens, which is positioned near the viewer's eye. The combination of these lenses allows for higher magnification and resolution compared to a simple microscope.
To compensate for the inversion of the image, compound microscopes often include additional lenses or prisms called "erecting lenses" or "erecting prisms" to correct the orientation and provide a right-side-up image to the viewer.
Compound microscopes are widely used in scientific research, education, and various fields of study, providing detailed and magnified views of microscopic samples.
