Description
Bresser Pirsch ED 15x56 WP Phase Coating binoculars (1721557) are premium binoculars! The Pirsch ED series is characterized by the fact that special optical glass with extra low dispersion ( Extra Low Dispersion Glass ) is used in the manufacture of lenses, which provides perfect color rendition of the image and a high degree of resolution. The refractive index of the beam with low dispersion glass is extremely low and depends little on the frequency of light (on the spectrum). All light waves are refracted by the same angle, providing impeccable image clarity. The use of such glass allows you to minimize such an annoying aberration as chromatism. The cost of ED glass is very high, which is why manufacturers of high-tech optics use it only in their premium products. Bresser Pirsch ED 15x56 WP Phase Coating binoculars (1721557) are high-brightness binoculars with an objective lens diameter of 56 mm, which are ideal for observations in twilight conditions, and are distinguished by both optical characteristics and the quality of the materials used. The optics meet all modern high requirements and standards: full multi-layered lens illumination ( Fully Multi-Coated ), protection against water and dust, nitrogen-purged, prisms made of high-quality optical glass BaK4 . The housing is made of lightweight and durable polycarbonate, covered with a rubber coating with profile knurling, characterized by high-precision adjustment of all components and components. The housing design with two hinges and an open bridge makes it possible to make the binoculars grip as reliable and comfortable as possible. All Bresser Pirsch ED optics also have a special UR coating (Ultimate Reflection Coating) to improve visibility in twilight. High-quality special phase correction coating ( Phase Correction ), which is applied to one of the surfaces of the prism rotating system in the form of the thinnest layers. Phase correction is necessary exclusively for the Roof optical system, since, passing through such a prism, the light flux is decomposed into two parallel beams of light waves, an out-of-phase shift of half the light wavelength occurs, which leads to a decrease in image resolution, as well as a decrease in contrast. Phase Correction corrects this displacement. As a result, the image is as clear and contrasty as possible. The cost of such a coating is very high, and the application process requires precision accuracy, so only well-known optics manufacturers can afford such a technological complication. The optics have a waterproof housing, sealed with an O-ring and protected from moisture penetration according to the international class IPX7 . Immersion in liquid for 30 minutes to a depth of 1 meter will not cause the device the slightest damage and will not affect its functionality. No weather conditions are terrible for such optics. Protection against fogging of lenses means that the inside of the case is blown with an inert gas, which eliminates the condensation of moisture on the internal surfaces during temperature drops. As a result, the optics do not fog up from the inside, and there is no corrosion of materials under the influence of moisture. The air is removed from the device and replaced with an inert gas (in this case, argon), which does not contain water vapor and does not condense. If you want to get a really high-quality binoculars that will not let you down in any weather conditions, at dawn and in the evening twilight - Bresser Pirsch ED 15x56 WP Phase Coating (1721557) is your choice.
