Distance objective
WebWith low-power objectives in the range 2X to 5X, the illumination cone will have a diameter between 6-10 mm, while the high-power objectives (60X to 100X) need a highly focused light cone only about 0.2-0.4 mm in diameter. With a fixed focal length, it is difficult to achieve this wide range of illumination cones with a single condenser. WebIn most areas of optics, and especially in microscopy, the numerical aperture of an optical system such as an objective lens is defined by = , where n is the index of refraction of …
