The Different Types of MicroscopesExploring the Top Four and MoreThere are several different types of microscopes used in light microscopy, and the four most popular types are Compound, Stereo, Digital and the Pocket or handheld microscopes.
Compound Microscopeis a type of microscope that used visible light for illumination and multiple lenses system for magnification of specimen. Generally, it consists of two lenses; objective lens and ocular lens. It can magnify images up to 1000X. Its magnifying power is equal to the product of ...
Light microscopy is probably the most popular form of microscopy encountered by students. It uses light from the visible spectrum and couples it with compound (serial) magnifying lenses to observe an object. Light Microscope There are several components to the modern light microscope that come togeth...
Bright Field: Light is focused by condenser lens onto the specimen. Transmitted light collected by the objective lens and focused onto the eye. What we see is a shadow of the specimen.Dark Field: Focuses a hollow cone of light onto the specimen. There is a dark field stop under the conde...
Figure 4. Assorted diatoms, a kind of algae, live in annual sea ice in McMurdo Sound, Antarctica. Diatoms range in size from 2 μm to 200 μm and are visualized here using light microscopy. (credit: modification of work by National Oceanic and Atmospheric Administration) ...
A lens magnifies by bendinglight(seerefraction). Optical microscopes are restricted in their ability to resolve features by a phenomenon calleddiffractionwhich, based on thenumerical aperture(NA orAN) of the optical system and thewavelengthsoflightused (»), sets a definite limit (d) to theoptic...

Using single-cell electrophysiology and serial block-face scanning electron microscopy, we show that two retinal ganglion cell types exhibit very different levels of surround suppression even though they receive input from the same bipolar cell types. This divergence of the bipolar cell signal occurs ...
