Black fly (Simulium yahense) with parasite (Onchocerca volvulus) emerging from the insect's antenna. 100x magnification by scanning electron microscope. A really clear and sharp electron microscope image on unpleasant yet encyclopedic subjects: biting insects, parasitology, and public health.

Reproduction of an early electron microscope constructed by Ernst Ruska in the 1930s. Many developments laid the groundwork of the electron optics used in microscopes. [2] One significant step was the work of Hertz in 1883 [3] who made a cathode-ray tube with electrostatic and magnetic deflection, demonstrating manipulation of the direction of an electron beam.
The microscope features a combination of optical and electron-optical images; the optical image enables a "Neverlost" function so operators may navigate to any point on the sample. Sample loading takes place in four seconds (to obtain the CMOS overview image) and 30 seconds into the vacuum space via rapid transfer technology (no conventional ...
InGaN/GaN nanorod array light-emitting diodes can be manufactured with dry etching or focused ion beam etching techniques. [6] Such LEDs emit polarized blue or green light [7] Three-dimensional nanorod structures have a larger emitting surface, which results in better efficiency and light emission compared to planar LEDs. [8]
Electron optics is a mathematical framework for the calculation of electron trajectories in the presence of electromagnetic fields. The term optics is used because magnetic and electrostatic lenses act upon a charged particle beam similarly to optical lenses upon a light beam .
In cryptozoology and ufology, "rods" (also known as "skyfish", "air rods", or "solar entities") are elongated visual artifacts appearing in photographic images and video recordings. Most optical analyses to date have concluded that the images are insects moving across the frame as the photo is being captured, although cryptozoologists and ...
A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM). Pronunciation is [stɛm] or [ɛsti:i:ɛm]. As with a conventional transmission electron microscope (CTEM), images are formed by electrons passing through a sufficiently thin specimen. However, unlike CTEM, in STEM the electron beam is focused ...
