Introducing the Kowa TE-11WZ II 25-60x / 30-70x Prominar Wide Angle Zoom Eyepiece, a remarkable addition to the Kowa eyepiece lineup designed for the TSN-99, TSN-88, TSN-880, and TSN-770 Spotting scopes.

This eyepiece breaks new ground with its innovative optical design, featuring 2XD lenses. At magnifications of 60X and 70X, images exhibit exceptional sharpness, while maintaining minimal chromatic aberration.

The eye relief of 17mm remains consistent across the entire range of magnification. Notably, the TE-11WZ II offers a 20% wider field of view compared to its predecessor, the TE-10Z.

When paired with TSN-88 / TSN-880 / TSN-770 series scopes, the TE-11WZ II provides magnifications of 25-60x, and when used with the TSN-99 series, it achieves 30-70x magnification.

This eyepiece is compatible with a range of Kowa spotting scopes including TSN-771*, TSN-772*, TSN-773, TSN-774, TSN-881*, TSN-882*, TSN-883, TSN-884, TSN-88A, TSN-88S, TSN-99A, and TSN-99S, as well as with a telephoto lens attachment.

Note that some products marked with an asterisk (*), such as TSN-771, TSN-772, TSN-881, and TSN-882, are no longer available, and using the telephoto lens requires the TP-88EC1 prism adapter.

The specifications provided here pertain to the TSN-880 / 99 series models. Specifics may vary depending on the spotting scope body being used.

      Nice piece of gear!

      Not cheap, but hey it's a top quality and that's important, right? Thats what I tell myself. I had the unforseen opportunity to test the waterproof and fogproof elements of this viewfinder, it passed the test.
