What are SEM, TEM, and confocal microscopes?

  SEM : Search Engine Marketing

Search engine marketing is a form of Internet marketing that involves the promotion of websites by increasing their visibility in search engine results pages primarily through paid advertising.


TEM : Transmission Electron Microscopy

Transmission electron microscopy is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid.


Confocal Microscopes

-Confocal microscopes have superior resolution -- much higher than conventional optical microscopes -- and are primarily used in measurement applications.

-Confocal microscopes can be categorized as either reflection-type or transmission-type based on the type of illumination used for imaging.
