Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.
In vitro bacterial culture
Moleskine texture color cover on white background
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.

Photomicrograph of Volvox globator, a green algae in various stages of development. Dark green spots are daughter colonies forming inside of parent colony. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
The Microscopic World. Tap water.
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.
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.
