The numerical aperture of a microscope objective is a measure of its ability to gather light and resolve fine specimen detail at a fixed object distance. Image-forming light waves pass through the specimen and enter the objective in an inverted cone as illustrated in Figure 1. NA is widely used to specify microscope objectives. NA allows for a precise calculation of the point spread function (PSF) and the modulation transfer function (MTF) The approximation for NA and f/# significantly breaks down at speeds faster than f/1.2. Application Example: Conflicting System Specifications
Numerical Aperture (N.A.): This is a number that expresses the ability of a lens to resolve fine detail in an object being observed. It is derived by a mathematical formula (n sine u) and is related to the angular aperture of the lens and the index of refraction of the medium found between the lens and the specimen. The numerical aperture of a microscope objective is the measure of its ability to gather light and to resolve fine specimen detail while working at a fixed object (or specimen) distance.
For example, a simple low-NA objective may contain a meniscus lens and an achromat. A high-NA objective typically contains a more complicated combination of various types of lenses of hemispherical, meniscus, achromatic doublet and triplet type. There are also reflective objectives, containing curved mirrors and no lenses. Our M- microscope objectives are corrected for a rear conjugate at 160 mm, and this family is the most popular family in the microscope objective offering. The M- series is available in a range of powers from 5x to 60x, either individually or as a complete set. High NA single-objective light-sheet. Alfred Millett-Sikking 1*, Kevin M.

Many neurons in the brain are closely related to sensing, learning and memory, however, they are usually densely packed. A high numerical aperture (NA) is important for TIRF microscopy. As a pioneer in TIRF microscopy, we offer a diverse lineup of objectives with a high NA, ranging from 1.45 to the world’s highest NA of 1.7* 1 and from 60x to 150x magnification. According to this web-page (Leica) an objective has a typical maximum collection angle of about 144 degrees. Doing the math for an oil immersion objective gives an NA of 1.44 as the maximum assuming 1.515 for the refractive index.
