Features of the Corrector PH
The adopted Wynne 3-group 3-element optical design extraordinary corrects coma-aberration from parabolic mirror surface, and eliminates spherical aberration. This realizes extremely uniform sharp pinpoint image of stars not only in the center but also to the edge of field of view.
This delivers very sharp images over the entire field of view with a large image circle (Dia. 44mm) which covers full-frame format.
The provided Vixen’s AS-coating (Maximum transmission rate at 99.9% per surface) on all lens surfaces and excellent matte inner surface finish minimizes light loss and generation of ghost and flare.
High quality control is assured by production in Japan and 100% inspection for elimination of the lens eccentricity.
