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.
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.
ascaris megalocephala cross section under the microscope showing an ovary - optical microscope x200 magnification
Cheyletiella blakei Mite - Small Cat pest view under a microscope
Algae under microscopic view, Diatoms, phytoplankton, fossils, silica, golden yellow
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.
Demodex folliculorum - parasitic mite on the eyelashes of a human eye, microscope
plant Zea Stem C.S. under light mircoscope with white background
Spore bags of helminthosporium contain 8 cells. This disease causes helminthosporiosis of wheat. Soon very small and quite harmful.
Trematode parasite under a microscope
Natural agate surfaces, suitable for backgrounds and wallpapers.
Photomicrograph of one celled amoeba. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
centropyxis aculeata (amoeboid organism) under the microscope - optical microscope x400 magnification

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.
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
close - up of a cat, isolated on white background
Some amoebas like this one form shells. Shell is composed of bits of rock (sand), diatom shells, and other debris. Fresh water. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Freshwater aquatic zooplankton and algae under microscope view
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.
Microscopic photo of a thin section of calcareous tufa of Holocene age.
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 abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Microscopic image of the operculum of a shrimp with possible disease. Research. Study. Laboratory. Aquaculture. Findings of disease in shrimp.
aspergillus under microscopy
Focused enlarge microscopic view of zoo plankton
Photomicrograph of sodium bicarbonate (baking soda) crystals in fern like patterns. Dry mount, 10X, transmitted polarized illumination. Note - very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
