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 »

An electron microscope has a higher resolution than a light microscope, which results in much finer detail of the specimen being viewed. Although an electron microscope can magnify a specimen up to 2 million times, a lig... More »

In microscopy, the depth of field refers to the range of distance that runs parallel to the optical axis where the specimen can move and still be viewed without negatively affecting the clarity of the object under observ... 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 »
