Optics efl
The effective focal length, also sometimes called equivalent focal length, is the inverse of the optical power of the optical system, and is the value used to calculate the magnification of the system. The imaging properties of the optical system can be modeled by replacing it with an ideal thin lens with the same EFL. See more The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, … See more For a thin lens in air, the focal length is the distance from the center of the lens to the principal foci (or focal points) of the lens. For a converging … See more Camera lens focal lengths are usually specified in millimetres (mm), but some older lenses are marked in centimetres (cm) or inches. Focal length (f) and See more For a thick lens (one which has a non-negligible thickness), or an imaging system consisting of several lenses or mirrors (e.g. a See more • Depth of field • Dioptre • f-number or focal ratio See more WebOptikos specifies the effective focal length (EFL) of its collimators using the true parabolic focal length. The segment is defined by the off-axis distance (OAD) and the clear aperture.The OAD locates the optical centerline (OCL) of the segment. Note: Collimators for OpTest ® systems use the standard 500 mm (13 inch) optical axis height.
