microscope

 [mi´kro-skōp]
an instrument used to obtain an enlarged image of small objects and reveal details of structure not otherwise distinguishable.
The light path of a darkfield microscope. From Hart and Shears, 1997.
acoustic microscope one using very high frequency ultrasound waves, which are focused on the object; the reflected beam is converted to an image by electronic processing.
binocular microscope one with two eyepieces, permitting use of both eyes simultaneously.
compound microscope one consisting of two lens systems whereby the image formed by the system near the object is magnified by the one nearer the eye.
darkfield microscope one so constructed that illumination is from the side of the field so that details appear light against a dark background.
electron microscope one in which an electron beam, instead of light, forms an image for viewing, allowing much greater magnification and resolution. The image may be viewed on a fluorescent screen or may be photographed. Types include scanning and transmission electron microscopes.
fluorescence microscope one used for the examination of specimens stained with fluorochromes or fluorochrome complexes, e.g., a fluorescein-labeled antibody, which fluoresces in ultraviolet light.
light microscope one in which the specimen is viewed under ordinary illumination.
operating microscope one designed for use in performance of delicate surgical procedures, e.g., on the middle ear or small vessels of the heart.
phase microscope (phase-contrast microscope) a microscope that alters the phase relationships of the light passing through and that passing around the object, the contrast permitting visualization of the object without the necessity for staining or other special preparation.
scanning electron microscope (SEM) an electron microscope that produces a high magnification image of the surface of a metal-coated specimen by scanning an electron beam and building an image from the electrons reflected at each point.
simple microscope one that consists of a single lens.
slit lamp microscope a corneal microscope with a special attachment that permits examination of the endothelium on the posterior surface of the cornea.
stereoscopic microscope a binocular microscope modified to give a three-dimensional view of the specimen.
transmission electron microscope (TEM) an electron microscope that produces highly magnified images of ultrathin tissue sections or other specimens. An electron beam passes through the metal-impregnated specimen and is focused by magnetic lenses into an image.
x-ray microscope one in which x-rays are used instead of light, the image usually being reproduced on film.

The best optical microscopes can focus on a single plant or animal cell.
It is inherent in optical theory, that when an object is viewed under the optical microscope, only one particular plane will be in focus.
Chapter 8, Photomicrography may have limited application since many optical microscopes have photographic units integrated into the microscopy unit.
Since electron waves have a wavelength equal to that of X rays (but are much easier to focus than X rays), an electron microscope should be much more powerful than an ordinary optical microscope.
The smallest detail a traditional optical microscope can reveal is about half the wavelength of green light, or 0.25 micrometres.
The various application segments for the optical microscope in the Europe region are semiconductor, life sciences, material sciences, nanotechnology, and others.

The SP9900+ Large Format 3D Optical Microscope is specially designed for the semiconductor packaging industry and offers major advantages over previous generations of optical microscope technology.
The VK-X Series 3D laser scanning microscopes combine the capabilities of SEMs and non-contact roughness gauges with the simplicity of an optical microscope. This system offers a 0.5 nanometer z-axis resolution with a magnification range spanning 200x to 24,000x.
Naturally, these systems are quite limited when compared to the cutting edge of electron microscopy; nevertheless, they still offer significant advantages over optical microscopes at a price that is not much more than that of a high-end optical microscope.
