Product Description

This Dioptrx accessory lens corrects for an astigmatism of 2.5 diopters. (This would be a"CYL" value of 2.50 in your eyeglass prescription.)  The lens rotates to match the orientation of your astigmatism, whether it is orthogonal (up and down) or oblique (at any angle intermediate between vertical and horizontal).

The lens replaces the rubber eyeguard at the top of any of the following long eye relief TeleVue eyepieces only: 26mm and 31mm Nagler type 5; 22mm, 27mm, 35mm, and 41mm Panoptic; 22mm, 40mm, and 55mm Plössl; all Radians (18mm thru 3mm); and all Nagler type 4 (22mm, 17mm, and 12mm). An adapter (DEA0001) is available to allow its use in 19mm and 24mm Panoptic eyepieces or the 20mm Type 5 Nagler. A separate adapter (DNA6000) is available to allow its use in all Type 6 Naglers.

The lens is precision-ground from optical glass, multicoated, and mounted in an anodized aluminum housing that locks into place on your eyepiece. A rubber eyeguard tops the Dioptrx lens.
