INDUSTRIAL MICROSCOPE

Inverted microscopes are useful for observing living cells or organisms at the bottom of a large container (e.g., a tissue culture flask) under more natural conditions than on a glass slide, as is the case with a conventional microscope.

In an upright microscope, the source of transmitted light and the condenser are located below the stage, pointing up. The objectives are placed on top of the stage, pointing down. The specimen is observed from the top through the lid of a petri dish or a coverslip.

A stereo microscope is a type of optical microscope that allows the user to see a three-dimensional view of a specimen. Otherwise known as a dissecting microscope or stereo zoom microscope, the stereo microscope differs from the compound light microscope by having separate objective lenses and eyepieces.

The polarized light microscope is designed to observe and photograph specimens that are visible primarily due to their optically anisotropic character.

Metallographic microscopes are used to identify defects in metal surfaces, to determine the crystal grain boundaries in metal alloys, and to study rocks and minerals. This type of microscope employs vertical illumination, in which the light source is inserted into the microscope tube

A biological microscope is generally a type of optical microscope that is primarily designed to observe cells, tissues, and other biological specimens. Multiple objective lenses can be attached, which gives these microscopes a magnification that can range anywhere from 10x - 1,000x or more.
