Encyclopedia of Optical Engineering
The depth of field of a system may or may not be limited by the optical diffraction
limit (and hence the F#). therefore a detailed discussion of alternative
calculations for this parameter is included. F-NUMBER The f-number, sometimes
written F# ...
f-number is the quantity that indicates the irradiance of the light incident on the
recording medium relative to the irradiance entering the lens. It's not only related
to the aperture size but also the focal length of the lens; it gives you an idea of the
...

Digital Nature Photography: The Art and the Science
The aperture in the lens is largest when the f-number is smallest and smallest
when the f-number is large such as f/22 or even f/32. This relationship confuses
beginning photographers because it is counterintuitive. Big f-numbers refer to
small ...

Image Sensors and Signal Processing for Digital Still Cameras
The F-number of a lens (F) is expressed as half the opening angle θ′ for the
focused light beams in Figure 2.1, as shown as in Equation 2.4. (2.4) F = 1 2sinθ
′ In reality, because this depends on the cross-sectional area of the light beams,

Laser Processing of Engineering Materials: Principles, ...
The focal number, or f -number, of a focusing optic characterizes its focusing
ability. The f-number defines the convergence angle of the beam: f = F d B (4.1)
where F is the focal length of the optic and dB is the diameter of the beam or
aperture, ...

Medical Infrared Imaging: Principles and Practices
A tradeoff has to occur to find the optimal f/number for the system. The table
below shows the tradeoffs between optics diameter, focal length, resolution, and
FOV. 5.5 Spectral Requirement The spatial resolution is heavily dependent on
the ...

Allen Mann. dairy = 2.44XF (1.15) where k is the wavelength and F is the lens F-
number. Detector arrays are specified by the detector size and the number of
pixels. Again, the smallest target that can be discerned is limited by the detector
size.

(D/f)2 °c I/A/2 Thus, smaller the f-number N the greater is the brightness of the
image, and, hence, the smaller is the exposure lime (or higher is the shutter
speed). The maximum diameter of the aperture is equal to the diameter of the
lens.
