Reading objective lens values

WebSome manufacturers have produced tables for converting convex radii to concave. The correction factors for radii for concave surfaces are greater than for convex surfaces and range from 0.02 mm for steep radii to 0.04 mm for flat. Thus, for lenses used in practice, it is sufficient to add 0.03 to the radius reading given by the keratometer. WebLarger objective lenses are not always the best choice.

WebJul 12, 2024 · Consequently, the high-NA objectives are those which use an immersion medium in place of air, such as oil or water. In reality, an NA of one with air between the specimen and the objective front lens is unachievable and therefore the highest NA of a ‘dry lens’ (i.e. a non-immersion objective) and is closer to 0.95. WebObjective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power, and (typically) oil immersion objectives, respectively. Let’s take a closer look at each of the different magnifications of objective lenses and when you would use them.
