WebFor any lens, not exclusively infinity-corrected objective lenses, it is possible to have a different working distance, and focal length. Take the telephoto lens below. A collimated ray bundle diverges after hitting a first negative lens. The diverging ray bundle is then focused by a second positive lens. WebInfinity lenses suffer from enhanced spherical aberration when used on a finite microscope system due to lack of a tube lens. The tube length in infinity-corrected microscopes is referred to as the reference focal length and ranges between 160 and 200 millimeters, depending upon the manufacturer.

Infinity Corrected Optics - Microscope World

WebThe curved interface of the lens collects light rays and focuses them to a point at the lens focal length. Infinity-corrected (4f) optical paths underlie all modern microscopes and provide the most flexible and uniform imaging system to date. Objectives like other lenses can have issues with errors like aberrations. WebAn infinity-corrected optical system basically has the following advantages because a parallel light beam passes between the objective lens and tube lens. A magnification … bottled up webcomic
