Delta Optical Extreme 7x50 ED binoculars
Zero-angle binoculars with constant magnification 7x and lens diameter of 50mm from the Extreme series featuring a solid construction. Multi-coated optics combined with a solid lens provide plenty of light and vivid and clear images. Thus, the binoculars can be used both during the day and after dark.
The body of the binoculars is made of durable metal and covered with a special rubber veneer, which, in addition to good grip, provides effective cushioning when the binoculars are dropped or bumped. The mechanics in the Extreme model can operate in a wide temperature range from -40 to 70 degrees Celsius.
.
An important feature Extreme is also full waterproofness and protection against fogging from the inside, in the form of pure nitrogen, with which the binoculars are filled.
Comfortable eyecups fit snugly around the eye sockets, cutting off light coming from outside. Thanks to its large size, the binoculars can be operated with gloves. Combined with the large exit pupil distance of the eyepieces, this ensures comfortable observation.
.
The binoculars use porroprismatic design and use low dispersion elements, and the prisms are made of high-quality glass BaK-4. All optical elements have been covered with anti-glare coatings (FMC). This guarantees over 90% light transmission throughout the system. The image is free of defects such as astigmatism or coma, and is perfectly flat thanks to proper distortion correction.
All Delta Optical Extreme models have a separate external focusing system for each eyepiece.
