2 convex lens.
Compound light microscopes have two types of lenses: objective lenses and eyepiece (or ocular) lenses. The objective lens is located close to the specimen and magnifies the image, while the eyepiece lens further magnifies and helps focus the image for the viewer.

Just One A Convex one a simple microscope is a simple magnifier?
It depends on the uses the lens are going to be put to. A lens may have a convex front and a flat back, or a convex front and a concave back, or even a convex surface on both front and back. Or even concave on both the front and back.Concave means bowed inwards.Convex means bowed outwards.
There are many good companies that one can chose to purchase quality used microscopes. This includes companies such as Metallography and Gradient Lens.
Pretty much any type of scientist uses microscopes. Microbiologists, paleontologists, pathologists, and many more.
There are several types of microscopes, including optical microscopes (such as compound and stereo microscopes), electron microscopes (such as scanning and transmission electron microscopes), and scanning probe microscopes (such as atomic force microscopes). Each type of microscope has unique characteristics and applications for viewing objects at various scales.
Antonie van Leeuwenhoek created a simple microscope with a single lens, known as a single-lens or simple microscope. This type of microscope was groundbreaking for its time and allowed Leeuwenhoek to observe and describe various microorganisms for the first time.
There are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, Transmission Electron Microscope, Dissection microscope, etc,but all together there are about 20 different types of microscopes.
Short Answer:A basic compound microscope has two lenses, one located near the specimen called the objective and a second located at the observation point that is called the eyepiece or ocular.Modern compound light microscopes can have a number of lenses and complex optics including multiples lenses in the eyepiece.Explanation:A single lens is enough to magnify a subject and that is a simple magnifying glass. To magnify an object a great amount with a single lens introduces distortions of various sorts which are much reduced by an appropriate combination of two lenses. As a result, greater magnification with image clarity can be achieved.The objective lens performs the task of collecting a great deal of light from the subject and does most of the magnification of the subject and the eyepiece adjusts the focus of the resulting light so the observer's eye can process the image. All modern compound microscopes have an eyepiece containing more than one lens providing additional image quality and magnification.There are many variations on the basic design that have evolved since its invention 400 years ago.
Robert Hooke is credited with inventing the compound microscope, which used a series of lenses to magnify images. He did not invent multiple microscopes, but his work in improving the design of the compound microscope contributed to advancements in the field of microscopy.
