Factors affecting microscope Imaging
Because of the objective condition, no optical system can produce the ideal image, and the existence of various difference influences the image quality. The following is a brief description of the differences.
Chromatic aberration is a serious defect of lens imaging, which occurs in the case of polychromatic light, the single color does not produce chromatic aberration. White light by the red Orange Green cyan violet seven kinds of composition, the wavelength of a variety of lights are different, so the refractive index through the lens is also different, so that the object of a point, in the square may form a stain.
Chromatic aberration generally has the position chromatic aberration, the magnification rate chromatic aberration. The position color errand looks like in any position to observe, has the color spot or the Halo ring, causes the like to be vague. The magnification color errand is like a colored edge.
