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. Webobjective lenses of varying magnification and numerical aperture are mounted on the rotating nosepiece. The nosepiece must click into place for the objective lens to be in proper alignment. You will notice that the lower power lenses (4X and 10X) are shorter than the high power lenses (40X and 100X), meaning that the clearance between the
