How many objectives did the virtual microscope have on its nosepiece?
The lens that you look through is the ocular (paired in binocular scopes); the lens that focuses on the specimen is the objective. Your microscope has four objectives of varying magnifications (4x, 10x, 40x, and 100x) mounted on a revolving nosepiece.
What are the 4 objective lenses on a microscope?
What Are the Different Magnifications of Objective Lenses?
- Scanning Objective Lens (4x)
- Low Power Objective (10x)
- High Power Objective Lens (40x)
- Oil Immersion Objective Lens (100x)
- Specialty Objective Lenses (2x, 50x Oil, 60x and 100x Dry)
How many objective lens are there?
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, total magnification is 40x (4x times 10x), 100x , 400x and 1000x.
How many objectives does a light microscope have?
5.19 Microscopes Ordinary light microscopes are equipped with three objective lenses (5 ×/10 ×, 40 ×, and 90/100 ×), and two ocular (5 ×, 10 ×) lenses.

What are the objectives of a microscope?
Objectives allow microscopes to provide magnified, real images and are, perhaps, the most complex component in a microscope system because of their multi-element design. Objectives are available with magnifications ranging from 2X – 200X.
How many objective lenses are there in a compound microscope?
two lenses
A compound microscope composed of two lenses, an objective and an eyepiece. The objective forms a case 1 image that is larger than the object. This first image is the object for the eyepiece.
What are the 3 objectives of a microscope?
Classification based on Magnification Essentially, objective lenses can be categorized in to three main categories based on their magnification power. These include: low magnification objectives (5x and 10x) intermediate magnification objectives (20x and 50x) and high magnification objectives (100x).
How many objective lenses are in a compound microscope?
A compound microscope composed of two lenses, an objective and an eyepiece. The objective forms a case 1 image that is larger than the object. This first image is the object for the eyepiece. The eyepiece forms a case 2 final image that is further magnified.
