Binoculars with constant 7x magnification and a 50mm lens diameter from the Extreme series, known for their robust design. The multi-coated optics together with a sturdy lens ensure ample light and produce vivid, sharp images. As a result, these binoculars are suitable for use both in daylight and after sunset.
The binoculars' body is fashioned from sturdy metal and encased in a specialized rubber veneer that not only enhances grip but also provides effective shock absorption if the binoculars are dropped or knocked. The mechanics of the Extreme model operate efficiently within a wide temperature range from -40 to 70 degrees Celsius.
.
Another key attribute of the Extreme series is its complete waterproofness and interior anti-fog protection, achieved with pure nitrogen filling.
The comfortable eyecups fit tightly around the eye sockets, blocking external light. Due to their large size, the binoculars can be handled while wearing gloves. Alongside the long exit pupil distance of the eyepieces, this feature ensures comfortable viewing.
.
These binoculars utilize a porroprismatic architecture with low dispersion components, with prisms crafted from premium-quality BaK-4 glass. All optical components are treated with anti-reflective coatings (FMC). This ensures over 90% light transmission throughout the system. Thanks to proper distortion correction, the image is free from defects like astigmatism or coma and remains perfectly flat.
Each Delta Optical Extreme model features an individual external focusing system for each eyepiece.
