You will immediately appreciate the excellent light transmission of the TE-10Z that was created to match the advanced optical system of Kowa's TSN 770/880 series of spotting scopes. This high performance zoom eyepiece has 10 lens elements and uses an aspherical lens to increase the field of view. Kowa covers this eyepiece with a limited lifetime warranty.
Note: This eyepiece will not fit the older Kowa 77mm TSN 1, 2, 3, or 4 spotting scope bodies.
