Caractéristiques du produit : ED Lentille à dispersion extra-faible : La lentille à faible dispersion ED (Extra-low Dispersion) est un verre spécial qui réduit l'aberration chromatique causée par la dispersion de la lumière des différentes longueurs d'onde visibles sur le télephoto, ce qui empêche la convergence de différentes longueurs d'onde sur le plan. Surtout dans les télescopes à longues focales, la lumière rouge et bleue est sujette à l'aberration chromatique en raison de différentes longueurs d'onde, ce qui réduit considérablement la netteté et la vivacité de l'image. Les lentilles ED réduisent considérablement la couleur causée par le téléobjectif en focalisant toutes sortes de longueurs d'onde de lumière sur le même point, ce qui rend l'image nette et vivante, avec un fort contraste et restitue la vraie couleur.

BAK4 revêtement de prisme multicouche : BAK4 est un verre avec un indice de réfraction supérieur à BK7, ce qui peut améliorer efficacement la transmission de la lumière, améliorer l'effet d'observation du télescope et rendre la vision plus claire, plus vive et sans distorsion.
