The objective lenses on a microscope collects light and brings the specimens into focus.
The lower power objective for the microscope is the small lense on the microscope. The size usuall ranges at 4x on the microscope.

The shortest objective lens in a microscope is typically referred to as the scanning lens.
A microscope with more than one lense, has an objective and an eyepiece.
Using high power objective lense
The iris on a microscope controls the amount of light entering the microscope objective lens. By adjusting the iris, you can regulate the brightness and clarity of the specimen being observed.
i think it is the light microscope or the dissecting microscope the technician will use only one objective lense x2
Multiply the magnification of the ocular and objective lenses. For an example, an ocular lense with mag 10X and an objective lense with mag 40X would result in a total magnification of 400X.
The objective lens on a microscope is used to magnify the specimen being viewed. It is responsible for producing a magnified image that can be further examined using the eyepiece lens. Different objective lenses offer varying levels of magnification to provide detailed views of the specimen.
The main parts of an optical microscope are: the eyepiece, objective lense and light source (sometimes a mirror). The objective lense has a short focal length so it produces an image a little bit up the microscope's tube which is then magnified by the eyepiece. Resolution is dependant on the numerical appeture of the lense and the wavelenght of the light source used.
