NOBLEX UWA ocular


 Extra class ultra wide-angle eyepiece

The NOBLEX® Ultra Wide-angle Anastigmatic eyepiece fea-tures an outstanding optical performance. It allows for a very high magni-fication and offers, concurrently, a very large field of view. This way, selected usage properties of a vario-eyepiece are implemented. The observer is provided with a matchless panorama impression at reduced distortion. The unique optical design brings features from progressive lens making into the eyepiece area. The special optical design that uses glasses with abnormal dispersion path as it is normally applied for extremely high-grade objects only, reduces the chromatic magnification difference significantly. The Ultra Wide-angle Anastigmatic eyepiece reflects point-shaped objects throughout the entire field of view stigmatically (stigma = point), i. e. in a point-shaped manner.
