WebSeveral different mountants with different refractive indices (R.I.) are available to mount diatoms for light microscopy but those with a high R.I. are generally best for mounting diatoms. For most diatoms high R.I. mountants provide greater contrast in the microscopic image and a better depth of field for a given Numerical Aperture (N.A.).
