An important point to understand when working with compound microscopes and their objective lenses is that Clean all objective lenses with lens paper and, if necessary, liquid lens cleaner. Place a Always start with a low power objective (4X or 10X) clicked into place.

For many years, objectives designed for biological applications from most manufacturers all conformed to an internationally recognized convention, a parfocal distance of 45.0 millimeters, the Royal Microscopical Society (RMS) standard defining the dimension of the thread that supports the objective lens in the nosepiece, and a mechanical tube length of 160 millimeters.

When a tube lens is paired the scan lens, the image plane is located between the scan and the tube lens; the depth of field at the sample is then controlled by the microscope objective. Spot Size Data A typical compound microscope will have four objective lenses: one scanning lens, low-power lens, high-power lens, and an oil-immersion lens. These lenses have a magnification power of four, 10, 40 and 100, respectively.

A Barlow lens is a diverging lens that alters the focal length of a microscope and, therefore, the field of view.
