WebI'm looking at datasheets (like this one from Sunex), and I'm wondering how a TTL for a lens is calculated. My understanding is that for a lens with a fixed focal length and approximated as a thin lens, the relationship is given by. 1/f = 1/u + 1/v. where u is the distance from object to lens, and v is the distance from lens to image (from Wiki ).

By focusing the lens for different working distances … In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes the range of angles over which the system can accept or emit light. By incorporating index of refraction in its definition, NA has the property that it is constant for a beam as it goes from one material to another, provided there is no refractive power at the interface. The exact definition of th…

WebIn optics, optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device: P = 1/f. [1] High optical power corresponds to short focal length.
