Demodex folliculorum - parasitic mite on the eyelashes of a human eye, 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.
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
Close up Plant epidermis with stomata or Leaf Epidermis (Stomata) under microscope.
Rock texture background High resolution or design art work.
Shoot meristem is the tissue in most plants containing undifferentiated cells. Meristematic cells give rise to various organs of a plant and are responsible for growth.
plant Dandelion Fuzz W.M. under light mircoscope with white background
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.
Freshwater aquatic zooplankton and algae under microscope view
Photomicrograph of Euglena species. Fresh water, California. Live specimen. Wet mount, 40X objective, transmitted bright field illumination.
Scabes mites eggs, Notoedres cati, from skin sample, microscopic view. Feline scabiosis.

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.
Dinophysis algae under microscopic view, Chromista, diatoms, phytoplankton, fossils, silica, golden yellow algae
Photomicrograph of stomata of leaf. Typical monocot distribution of stomata. Epidermis peeled from iris leaf. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Micrograph of just the tips of the papillose peristome teeth of a moss,Pohlia nutans, at 200x
Squash preparation of plant cells stained to reveal chromosomes, various stages of mitosis are visible. 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 aberration is inevitable in light microscopy, but has been kept to a minimum in this image.
Light microscope micrograph of a retina stained with the Golgi method showing an amacrine cell with dendrites ending in the inner plexiform layer. On top, cell bodies of bipolar cells and photoreceptors can be seen.
