  2. Index-matching material - Wikipedia

    en.wikipedia.org/wiki/Index-matching_material

    Typical oils used have an index of refraction around 1.515. [2] An oil immersion objective is an objective lens specially designed to be used in this way. The index of the oil is typically chosen to match the index of the microscope lens glass, and of the cover slip. For more details, see the main article, oil immersion.

  5. Impedance matching - Wikipedia

    en.wikipedia.org/wiki/Impedance_matching

    For example, in order to match an inductive load into a real impedance, a capacitor needs to be used. If the load impedance becomes capacitive, the matching element must be replaced by an inductor. In many cases, there is a need to use the same circuit to match a broad range of load impedance and thus simplify the circuit design.
