BRESSER DACHSTEIN ED-APO 16-50X66 SPOTTING SCOPE

Bresser Dachstein ED-APO 16-50x66 spotting scope
Bresser Dachstein ED-APO 16-50x66 spotting scope is part of the the new top-line of Bresser spotting scopes! The scope is rugged, waterproof and has undergone a full multi-coating process. This is aside from the fact that these spotting scopes feature exclusive ED optics. Colour trueness, contrast and sharpness are far higher than in standard lenses. ED glass lenses (ED = Extra low Dispersion) are produced using a special process to reduce the so-called secondary spectrum to a minimum. The optics of the Bresser Dachstein ED-APO 16-50x66 spotting scope are simply superb.

Precise focus: coarse and fine mechanism
Additionally, the Bresser Dachstein ED-APO 16-50x66 spotting scope is equipped with a coarse and fine focusing mechanism drive ensuring smooth and precise focusing. This feature is only available on Dachstein spotting scopes.

Available with 16x to 50x magnification
This version of the Bresser Dachstein spotting scopes has a minimum magnification of 16x, making it ideal for use in the field, for shooting, and for keeping track of people. If zooming is needed, you can turn the eyepiece to zoom up to 50x, revealing even the smallest details. With a 66mm lens, you get true colours, and a clear picture.

APO lenses and ED coating: colour true and sharp to the edges
APO means apochromatic. This means that the lens is better corrected for chromatic aberration. A simple lens will have a different focus depending on the wavelength of light. So for the colour blue the lens will have a different focal length than for red. The use of multiple element lenses plus some special types of glass such as ED glass made of fluorite (this is actually not glass but an artificially grown crystal, very expensive and difficult to be worked) ensures that the focal point for all wavelengths coincide.Note this is not an easy job and this will translate itself in a higher cost, especially in fast lenses where this problem is much more noticeable.For non-APO lenses the colour error can best be seen in the purple band at transitions from very bright to very dark. This band is caused by chromatic aberration. Ultimately, this aberration will cause a general decrease in sharpness and contrast.
