Abbe number. In optics and lens design, the Abbe number, also known as the V-number or constringence of a transparent material, is an approximate measure of the material's dispersion (change of refractive index versus wavelength), with high values of V indicating low dispersion. It is named after Ernst Abbe (1840–1905), the German physicist ...

An optical instrument is said to be diffraction-limited if it has reached this limit of resolution performance. Other factors may affect an optical system's performance, such as lens imperfections or aberrations, but these are caused by errors in the manufacture or calculation of a lens, whereas the diffraction limit is the maximum resolution ...
The last non-EOS based SLR camera produced by Canon, the Canon T90 of 1986, is widely regarded as the template for the EOS line of camera bodies, although the T90 employed the older FD lens-mount standard. For a detailed list of EOS Film and digital SLR cameras, see Canon EOS.
Canon EOS. Canon EOS ( Electro-Optical System) is an autofocus single-lens reflex camera (SLR) and mirrorless camera series produced by Canon Inc. Introduced in 1987 with the Canon EOS 650, all EOS cameras used 35 mm film until October 1996 when the EOS IX was released using the new and short-lived APS film. In 2000, the D30 was announced, as ...
Abbe condensers are difficult to use for magnifications of above 400X, as the aplanatic cone is only representative of a numerical aperture (NA) of 0.6. This condenser is composed of two lenses, a plano-convex lens somewhat larger than a hemisphere and a large bi-convex lens serving as a collecting lens to the first.
The 70-200 mm f/2.8L lens. Canon's series of L lenses (Luxury lenses) are a professional line of photography lenses made by Canon.Canon has sold zoom and prime L-series lenses for the discontinued FD lens mount, for the current EF lens mount used on all Canon EOS SLR cameras and for the RF mount used on mirrorless interchangeable-lens cameras.
In optics, the Abbe sine condition is a condition that must be fulfilled by a lens or other optical system in order for it to produce sharp images of off-axis as well as on-axis objects. It was formulated by Ernst Abbe in the context of microscopes. [ 1] The Abbe sine condition says that. the sine of the object-space angle should be ...
