The photograph contains many tadpoles of a glass frog.  The photo was taken at night.  The tadpoles can be seen very clearly when zooming in.  They are on a palm leaf
centropyxis aculeata (amoeboid organism) under the microscope - optical microscope x400 magnification

Protozoa and Green Algae in waste water under the microscope.
Taenia Pisiformis Section under light microscope 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.
Freshwater aquatic zooplankton and algae under microscope view
Spore bags of helminthosporium contain 8 cells. This disease causes helminthosporiosis of wheat. Soon very small and quite harmful.
In vitro bacterial culture
Freshwater zooplankton Rotifer or Rotifera Euchlanis by microscope. Wheel animals. Benthic.
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.

(Physa acuta) Gastropod mollusk, an invader in the south of Ukraine on a leaf of a floating plant
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.
