Infinitycorrected

Infinitycorrected refers to a type of optical lens design that corrects for chromatic aberration across a wide range of wavelengths, particularly those encountered in astronomical imaging. Traditional lenses suffer from chromatic aberration, where different colors of light are focused at slightly different points, leading to blurry or colored fringes around stars and other celestial objects. Infinitycorrected optics are specifically engineered to bring these different wavelengths of light to a common focal plane.

This correction is often achieved through the use of multiple lens elements made from different types of glass, each with distinct refractive properties. By carefully combining these elements, optical designers can cancel out the chromatic dispersion that would otherwise occur. The term "infinitycorrected" implies that the lens is designed to focus light from distant objects, such as stars and galaxies, onto the sensor or eyepiece. This is crucial for astronomical telescopes and other instruments where the subjects of observation are effectively at an infinite distance. The use of infinitycorrected lenses is paramount for achieving sharp, accurate images in applications where detail and color fidelity are essential.
