Oil-immersion objective lenses look superficially identical to non-oil-immersion lenses. In light microscopy , oil immersion is a technique used to increase the resolving power of a microscope . This is achieved by immersing both the objective lens and the specimen in a transparent oil of high refractive index , thereby increasing the numerical ...
The results were difficult to interpret and not reliable, because of inaccurate results that were not standardised between laboratories. [25] Dilution has been used as a method to grow and identify bacteria since the 1870s, and as a method of testing the susceptibility of bacteria to antibiotics since 1929, also by Alexander Fleming.

Nocticron („Night-time“ from latin nox, noctis „night“ and ancient Greek kronos „time“ [1]) is the brand name of Leica lenses with an extreme speed of f/1.2. Because of the large aperture size and its image stabilisation system it is possible to take images with relatively short exposure time especially in available light situations.
