When the slides are observed under a microscope, the researcher counts the number of grains of each pollen taxon. This record is next used to produce a pollen diagram. These data can be used to detect anthropogenic effects, such as logging, [29] traditional patterns of land use [30] or long term changes in regional climate [31]
The microscope: used for visualising minute structures including microbes: Various stains: used to stain microscopic slides to get contrast Hot air oven: used in sterilizing instruments for various aseptic procedures, specially if that can not be autoclaved like powders Koch's or Arnold's steam sterilizer: used for steam sterilization A ...
A microscope slide is a thin flat piece of glass, typically 75 by 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope. Typically the object is mounted (secured) on the slide, and then both are inserted together in the microscope for viewing.

Polarizing microscope operating principle Depiction of internal organs of a midge larva via birefringence and polarized light microscopy. Polarized light microscopy can mean any of a number of optical microscopy techniques involving polarized light. Simple techniques include illumination of the sample with polarized light.
Rays (black) coming from the object (red) at a certain angle and going through the cover-slip (orange, as is the slide at the bottom) can enter the objective (dark blue) only when immersion is used. Otherwise, the refraction at the cover-slip-air interface causes the ray to miss the objective and its information is lost.
Digital pathology is a major part of pathology informatics, and encompasses topics including slide scanning, digital imaging, image analysis and telepathology.. Digital pathology is a sub-field of pathology that focuses on managing and analyzing information generated from digitized specimen slides.
