The optical systems re-designed on the basis of the Carl Zeiss Advanced Optics System (AOS) use glass material containing fluorine ions, which provides the objective lenses with superachromatic properties - with natural color rendition down to even the finest nuances, superb detail recognition and no color fringes. These optics are LotuTec coated.
Two wide-angle eyepieces with fixed magnifications and one zoom eyepiece are available - including a bayonet mount with a safety catch for rapid eyepiece change. The ergonomically designed dual focusing system features two wheels for fast focusing and, if required, fine focusing with just one hand. Additional features include rotatable, generously dimensioned tripod bracket; extensible sunshade with sight and leakage test and nitrogen filling.
Needless to say, the scopes are all provided with Carl Zeiss T* multilayer coating on all glass-to-air surfaces for maximum transmission and natural color rendition, and Carl Zeiss P coating on the roof surfaces of the reversal prisms for maximum resolution.
Available in a choice of straight-through or angled-bodies, both models include extended eye relief and twist-up eyecups. Use a straight-through version to observe birds on the ground or at eye level. The angled-eyepiece version eliminates neck strain that occurs when viewing birds perched high in a tree. This is also the best model to use with a tripod, as it can positioned lower to the ground.
Housed in an alloy aluminum body, both models are corrosion-resistant and are the lightest in their class. The robust, water and dust-proof casing protects the Diascope when used in rough terrain or tropical climates even with the eyepieces removed. Rapid changes in temperature have no influence on its optical performance as nitrogen filling prevents fogging of the lens elements inside the casing.
Diascope 65 T* FL - The compact, very lightweight spotting scope: Like its big brother, this compact spotting scope contains a world renown optical system, provides the same outstanding image quality, and meets the needs of even the most professional user. With a length of just 11.81 inches and weighing a mere 2.43 pounds, it is ideal for observation in locations with long approach routes. The lower weight also allows the use of a lighter tripod.
