In an objective light
WebLight that is returned upward can be captured by the objective in accordance with the objective's numerical aperture. After entering the objective, light then passes through the partially silvered mirror (or in darkfield, through the elliptical opening). In the case of infinity-corrected objectives, the light emerges from the objective in ... Weblight, electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10−11 metre to radio waves measured in metres. Within that broad spectrum the wavelengths visible to humans occupy a very narrow band, from …

Light intensity passing through this system varies above and below an average value, which is then modulated. Objectives useful for modulation contrast can cover the entire magnification range of 10X, 20X, and 40X.
