ED glass - Extra Low Dispersion glass

Binoculars and optics made from ED glass

ED GlassIn addition to the coating of optics, the glass quality or type of glass is one of the most important quality factors for binoculars and riflescopes " More info effectively compensates for the Chromatic aberration (chromatic aberration = different coloured parts of a beam of light are refracted to different degrees - can be clearly seen as a colour fringe along edges) and thus contributes to images with superior contrast and outstanding resolution with. The reward is exceptionally detailed, true-colour and vivid illustrations.

Under ED glass (Extra-low dispersionED glass effectively compensates for chromatic aberration (chromatic aberration = different coloured parts of a light beam are refracted to different degrees - can be clearly seen as a colour fringe along edges) " More info Glass) is a fluoride-rich glass melt (FL glass) from which apochromatically corrected LensesThe use of aspherical lenses leads to a reduction in the overall length of the binoculars and in some cases to a significant reduction in weight.
