Pine Root C.S. under light mircoscope with white background
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.

Transmission electron microscope micrographs  showing the aspect of muscle fiber sarcomere components in longitudinal (below) and transverse (above) sections at the Z-line, I and A bands and H zone
Orange Square wooden box filled with orange book replicas
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.
Epithelial Cells in urine sediment.
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
