AT A GLANCE

Field flattener lenses deliver an almost flat, completely distortion-free image – right up to the edges. Pin-sharp contours, high-contrast, and true-to-life images, allow you to make out every detail.

Innovative lens coatings provide excellent color rendering with high light transmission. The STC is constructed as a single unit and cannot be separated into eyepiece and objective modules
