Magnification Miami University

In case of a 100X lens, the distance between the coverslip and the objective lens is very less which makes the angular aperture 90°. Thus, the sinƟ is maximum, i.e. 1. This implies that if we want to further increase the numerical aperture, we need to increase the refractive index. To do so, we use immersion oil which has a greater refractive index to that of water (1.33) or air (1.0003).
