Ocular TE-10Z 20x60 para series TSN 880 y TSN 770

Powerful zoom eyepiece 20-60x
High-performance zoom eyepiece with 10 lens elements in 6 groups.

Using an aspherical lens to increase the field of view, which has traditionally been a drawback of zoom eyepieces.
The design ensures a wide field of view through the entire zoom range and a flat field all the way to the edge of the lens. The newly developed optical design reduces the deterioration of the image at high magnifications.
