TE-80XW Extreme Wide eye piece to fit the Kowa TSN-99, TSN-880 and TSN-770 mm series spotting scopes

The TE-80XW 40x extreme wide eyepiece produces a wide 80-degree field of view allowing for a stunning experience. The TE-80XW delivers a 40x magnification and a field of view of up to 37m at 1000m distance allowing you to quickly find a subject. A flat resolution is maintained throughout the entirety of the 80-degree field of view thanks to the field flattener lens incorporated into the optical design.

The TE-80XW offers a 40x magnification and a field of view of 39m when paired with the TSN-99 or a 35x magnification and a field of view of 45m when paired with the TSN-880 or 770 series spotting scopes at 1000m distance.

The eyepiece benefits from Kowa’s unique KR coating that limits chromatic aberration and repels dirt, moisture and dust from building on its surface. It is also fully waterproof and sealed against the elements.

Kowa TSN-99 / TSN-880 / TSN-770 series spotting scopes.
