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.
Dinophysis algae under microscopic view, Chromista, diatoms, phytoplankton, fossils, silica, golden yellow algae
marine green algae under the microscope - optical microscope x100 magnification
Cheyletiella blakei Mite - Small Cat pest view under a microscope
Happy tardigrade- the water bear- a micro-animal living in moss that looks like it's smiling and dancing, from Shenipsit State Forest in Somers, Connecticut.
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.
