Numerical Aperture - RP Photonics

- The numerical aperture of an optical system is defined as the product of the refractive index of the beam from which the light input is received and the sine of the maximum ray angle against the axis, for which light can be transmitted through the system based on purely geometric considerations ( ray optics ):

What is Aperture? Understanding Aperture in Photography
- https://photographylife.com/what-is-aperture-in-photography
- Aperture can be defined as the opening in a lens through which light passes to enter the camera. It is expressed in f-numbers like f/1.4, f/2, f/2.8 and so on to express the size of the lens opening, which can be controlled through the lens or the camera.

- The numerical aperture is the same concept as f/number but on the front of the lens. Whereas the f/number determines the image resolution, the numerical aperture determines the object resolution. Numerical aperture is the angle that the aperture makes with the front focal point. The basic form of numerical aperture is determined by two measurements - the size of the aperture …
The Numerical Aperture - SPIE

- The numerical aperture controls the number of diffraction orders that are used to form the image, and thus the quality of the image. For a lens with magnification, there is an object side and an image side numerical aperture, and the ratio of the two is the magnification factor.

- The numerical aperture is dependent upon the angle of the inverted cone of illumination entering the objective aperture, as well as the refractive index of the imaging medium: NA(Obj) = n(sin(θ)) (2) where θ is the objective angular aperture and n is the refractive index of the medium (air, water, or oil) between the objective and the specimen. The image resolution, (D) is defined by …
Aperture numbers - digital photography
- https://digital-photography.com/camera/aperture-number.php
- The aperture number or f-number is the ratio of the focal length and the diameter of the lens opening. An f-number of 4 means that the lens opening is a quarter of the focal length, 8 is an eighth – i.e. less. Hence: larger f-number → smaller aperture and vice versa.
Resolution and Numerical Aperture - Teledyne Photometrics
- https://www.photometrics.com/learn/microscopy-basics/resolution-and-numerical-aperture
- The NA is calculated from the refractive index in front of the objective and the half-angle (θ) of light that the lens transmits from the sample towards the detector. NA = n * sinθ. The more open the aperture, the more angles of light that can pass …
What Is An F Number? An Aperture Lesson
- https://photographycourse.net/aperture-f-number/
- Aperture F Number (f-stop) We’ve already taught that the aperture is measured in f-stops and that the smaller the number, the bigger the opening. The reason for this is because each measurement is actually the fraction of f/ (number) IE f/1.4, f/2, f/2.8, f/4, f/5.6, etc. The f in Aperture F Number simply stands for the lens’ focal length.
