Esprit 80ED APO Triplet

Esprit 80ED APO Triplet

    Esprit 80ED, 100ED, 120ED and 150ED Super APO refractors have a doublet field flattener to get a flat field and minimize aberration and distortion. Their wide 48mm opener ensures a larger and clearer aperture and also extremely minimized halation. 

    Connect the triplet and doublet field flattener with a high precision thin thread to keep the optical axis perpendicular to the image.
