Medical Definition of Immersion liquid
1.
Any liquid occupying the space between the object and microscope objective. Such a liquid is usually required by objectives of 3-mm focal length or less. For best results (i.e., resolution) the liquid should be used between the condenser and the microscope slide. Immersion objectives for transmitted light are designed for use with either oil, glycerin, or water, the refractive index of the liquid and the coverslip (if any) being the determining factor. The liquid and the front lens of the objective should ideally coincide in index and in dispersion value.
