Freshwater aquatic zooplankton and algae under microscope view
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
Cheyletiella blakei Mite - Small Cat pest view under a microscope
centropyxis aculeata (amoeboid organism) under the microscope - optical microscope x400 magnification
Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens. Depth of focus is extremely shallow (just a few microns). Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic aberration is inevitable in light microscopy, but has been kept to a minimum in this image.
Notoedres cati under the microscope. Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati.
Trematode parasite under a microscope
The Cladocera are an order of small crustaceans commonly called water fleas on the slide under microscope.

Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
Mix parasite.
Natural agate surfaces, suitable for backgrounds and wallpapers.
Spore bags of helminthosporium contain 8 cells. This disease causes helminthosporiosis of wheat. Soon very small and quite harmful.

Taenia Pisiformis Section under light microscope with white background
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
amazing inhabitants of the microworld under a microscope
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.

Algae under microscopic view, Diatoms, phytoplankton, fossils, silica, golden yellow
Photomicrograph of Paramecium caudatum. Consists of only one cell. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
