Kowa 20-60x Zoom Eyepiece for 88mm and 77mm Kowa Spotting Scopes

Description

Kowa 20x-60x Zoom Eyepiece

This high performance zoom eyepiece has 10 lens elements in 6 groups and uses an aspherical lens to increase the field of view, which as traditionally been a drawback of zoom eyepieces.  This design ensures a wide field of view through the entire zoom range and a flat field all the way to the edge of the lens.  The newly developed optical design reduces the deterioration of the image at high magnification.  For use with Kowa 88mm and 77mm Spotting Scope Bodies
