Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power. Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4X, 10X, 40X and 100X powers. When coupled with a 10X (most common) eyepiece lens, we get total magnifications of 40X (4X times 10X), 100X , 400X and 1000X.
A binocular microscope has one optical path starting at the microscope objective. The optical path is split into two paths that are then brought to your eye. If your microscope has two eyepieces and one standard objective then you have a binocular microscope.A trinocular microscope works in the same manner, but the optical path is split into three paths, two for your eyes and a third port mostly used for a video/camera connection.In a stereo microscope, there are two paths starting at the microscope objective that travel parallel up to your eyepiece.There is an advantage to using a stereo microscope; it is the depth perception.f your microscope has two eyepieces and one standard objective then you have a binocular microscope. A trinocular microscope works in the same manner, but the optical path is split into three paths, two for your eyes and a third port mostly used for a video/camera connection.
