Parfocal microscopes maintain focus throughout real-time magnification changes. These microscopes also remain focused when the user rotates objectives. This capability is a function of the lens and is a particularly popu... More »

The low-power objective on a microscope is the shortest or second shortest objective lens found on standard laboratory microscopes. Low-power objective lenses typically add 10x to the magnifying power of the microscope. More »

Light microscopes reveal the structures of living cells and tissues, according to HowStuffWorks.com. Using light microscopes, scientists have greatly increased human knowledge in the biomedical science fields. Even as th... More »

Light microscope disadvantages include limited resolution, lower magnification and poorer surface view of the specimen. Compound light microscope require the user to adjust to optical inversion, meaning the specimen will... More »

The microscope is a device used to view very small objects by magnifying the image. This can be done through optical and non-optical means. More »

The revolving nosepiece of a microscope is called the turret. The turret is the part of a compound microscope that holds the objective lens. It can be rotated easily to switch between lenses of different powers. More »

A diaphragm on a microscope is the piece that enables the user to adjust the amount of light that is focused under the specimen being observed. A diaphragm is typically found on higher-power microscopes versus less expen... More »
