The widest field of view ever seen from a sporting point of view. Wide field eyepiece with fixed magnification dedicated to the TSN99 (40X) and TSN770, TSN880 (35X) spotting scopes. For the top of the range Kowa products, only an eyepiece with the same high optical and mechanical characteristics would be able to make the most of the performance of the telescope or telephoto lens used. The use of two ultra-low dispersion XD glasses guarantees sharp and contrasted images even at high magnifications. Chromatic aberration is minimized, imperceptible. The 17mm eye relief also remains constant over the entire magnification range, a feature reserved only for high-level eyepieces.

EXTREME WIDE ANGLE: see more. Immerse yourself in the scene with a magnification of 40x and a field of view of 37m (TSN-99) or with a magnification of 35x and a field of view of 45m (TSN-880/770) at a distance of 1000m. Frame the scene quickly and don't miss a single detail.

A true innovation. Kowa opticians have succeeded in creating one of the most immersive visual experiences ever seen in the world of precision sports optics. Thanks to a sophisticated optical scheme we can define the vision through the Kowa TE-80XW Extreme wide angle eyepiece with the nickname "leaves you breathless".

With a built-in field flattener and an XD lens, the eyepiece produces uniform and perfectly sharp images across the entire field of view. The presence of the Kowa XD lens guarantees the virtual absence of chromatic aberration.
