Description
Hawke Endurance binoculars with an objective lens diameter of 56 mm are designed for low visibility conditions and are clearly distinguished by both optical characteristics and the quality of construction and materials. The frame is made of lightweight polycarbonate, rubber coated with a humic coating with profile knurling and is characterized by high precision of fit of all assemblies and storage components. The optical characteristics also match the body. The prisms operate with a phase-regulating coating, without which today's high-end binoculars of the Roof system are inescapable. The lenses have an intense coating that brightens, in green tones, and the optical system as a whole is characterized by a wide field of view, a large field of view and a minimal focusing distance. If you want to get an effective, clear pair of binoculars that won’t let you down in the face of all weather conditions, the Hawke Endurance 8x56 is your choice.
Phase Correction is a special phase-correcting coating that is applied to one of the surfaces of the prism wrapping system in the appearance of very thin balls. Phase correction is also necessary for the Roof optical system; fragments passing through such a prism, the light flow is decomposed into two parallel beams of light fibers, and the phase displacement occurs by half the amount light color, which leads to a change in the separation of the image, as well as a decrease in contrast. Phase Correction corrects the error. As a result, the image is as clear and contrasting as possible. The quality of such a coating is very high, and the application process requires precision precision, which is so technologically advanced that optics manufacturers can only afford it. Today, without a phase-correcting coating, the design of a high-viscosity optical device of the Roof prism system is practically inconceivable. 
The highly spherical wide-smooth coating of Hawke optics, however, ensures high light transmittance across the entire visible spectrum and provides high contrast and color rendering in natural tones.
BAK4 (Barium crown) is a special type of optical glass, which is used for the production of prisms for optical devices. This material has a lower dispersion coefficient (light dispersion), which is less suitable for budget models. As a result, chromatic aberration is noticeably reduced (iris at sharp intervals between the transition from dark to light). In addition, a clear indicator of light bending allows you to eliminate vignetting (the phenomenon of trimming the light beam along the edges), which ensures uniform lightness of the image across the entire field of view.
Waterproof - means that the optics are sealed with an O-ring and are protected from moisture penetration when immersed in liquid for 3 minutes to a depth of 1.5 meters. The static pressure of the liquid at a depth of 1.5 meters will not cause the slightest damage to the device and will not affect its functionality. Such optics are not afraid of any weather conditions.
Fogproof - means that the body is filled with dry nitrogen N2 in the middle, which prevents condensation of moisture on the internal surfaces at a temperature gradient, daily fogging in the middle, and therefore does not cause corrosion of the materials the vologgers are pouring in. The air is removed from the device and replaced with an inert gas (in this case, nitrogen N2), which does not allow water vapor in its storage and does not condense.
Today, polycarbonate is increasingly being used for housings of optical devices. This material is completely justified by its minimal strength, chemical, thermal, mechanical resistance and ease of processing. Polycarbonate housings are lightweight and shockproof. The stench does not attract additional expensive finishing treatment, such as anodizing or prefabricating.
- Possibility of mounting a tripod.
