Description
The Bresser binocular line has been expanded with a high-class model of the Pirsch series with improved optical and operational characteristics - Bresser Pirsch 15x56 WP Phase Coating (1721556) , which stands on a par with the best models in its class. The Bresser Pirsch 15x56 WP Phase Coating (1721556) binoculars are high-speed 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, protection against water and dust, nitrogen purged, prisms made of high-quality BaK4 optical glass. The body is made of lightweight and durable polycarbonate, covered with a rubber coating with profile knurling, and is characterized by high precision of fit of all components and components. The design of the housing with two hinges and an open bridge makes it possible to make the grip of the binoculars as reliable and comfortable as possible. All Bresser Pirsch optics also have a special UR coating (Ultimate Reflection Coating) to improve visibility at dusk. A 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 and 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. Today, without a phase-correcting coating, the design of a modern high-quality optical device of the Roof prism system is practically unthinkable. Water protection - means that the optics are 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 slightest damage to the device and will not affect its functionality. No weather conditions are scary for such optics. Protection against fogging of lenses - means that the housing is blown from the inside 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. 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 pair of binoculars that will not let you down in any weather conditions, at dawn and in the evening twilight - Bresser Pirsch 15x56 WP Phase Coating (1721556) is your choice.
