Question

how would you advice someone to use the three objective lenses on the nosepiece

Answer 1

Use

When observing an object with the microscope, the user starts with the lowest setting. When the user needs a higher magnification, the user turns the nosepiece to the next highest level. It is important to not turn the nosepiece by grasping the lenses as this may cause damage. Some microscopes provide a special lens that works with oil to provide a higher definition image. To use this lens, the user places immersion oil on top of the slide and puts the lens close to the slide. The oil forms a bond between the slide and the lens.

Care

Through normal use, especially when using oil or water on a slide, the lenses attached to the revolving nosepiece may become dirty. The proper way to remove dust from the lenses is to use lens tissue to gently wipe the surface. Compressed air also can be used. Users should not blow on the lens or eyepiece to remove dust, as this can put moisture from the breath on the nosepiece and lenses. When using immersion oil, users should use lens tissue to wipe the oil from the lens, nosepiece and other parts of the microscope immediately after completing the viewing of the slide.

Answer 2

we can use three objective lenses on the nose piece:

Explanation:

• Objective lenses are the optical element closest to the specimen.

• Objectives ve glasses is used in mucroscope telescope ectc.

• Usually we can find 3 or 4 objective lenses on a microscope . these are consist of 4x, 10x, 40x and 100x powers by changing these we can magnify more.

Here the function of nose piece is that it is one of the parts of a microscope it is responsible for holding the objective lenses. they can be used to change the magnification as well by changing the objective lense by revolving the nosepiece.
