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.

Stereoscopic OCC images are similar in appearance to DIC images on a compound microscope. Both techniques show transitions in refractive indices within the specimen and depict them in a way that reveals the specimen's dimensionality, topography, and morphology.

Simple microscope limitations can be overcome using a compound microscope, in which two lenses, the ocular and the objective lens, determine magnification.
The two magnifying lenses in a compound microscope are the objective--the primary magnifier close to the sample--and the eyepiece.
