Steiner Peregrine Outdoor Bino's
The Bak4 Roof Prisms are Phase Corrected to ensure accurate color representation and improved contrast, while fully multi-coated lenses maximize light transmission to provide crisp high-contrast views. With the 2050 (8x42) model, the moderate 8X Magnification ensures a wide Field Of View and Exit Pupil to make scanning easier with minimal head movement and ensures steady images without the distracting hand shake that can interfere with the view. For the 2051 (10x42) model, the higher 10X Magnification reveals greater long-distance detail, making it ideal for viewing far-off subjects like Raptors, Waterfowl and Wildlife, especially in open country. These optical features are further enhanced by Steiner's Fast Close focus and distance-control systems that make focusing at all distances fast and easy, so you can quickly react when necessary. Fold-down rubber winged eyecups help you focus on the image by blocking your peripheral vision and prevents stray light from interfering. Images appear sharper and clearer with brighter contrast.
Steiner's Peregrine series of supreme roof prism outdoor birding binoculars achieve their remarkable brightness & color balance by using a dielectric prism coating. More than forty layers of titanium oxide and other rare minerals are alternately applied to the glass surfaces, a Broad-Band Coating (BBC) resulting in superior light transmission performance over an expansive color range. They're also phase corrected for the lowest distortion, sharpest possible imagery. The bottom line to all this technological jargon; you'll see colors more vibrantly, allowing discovery and identity of species in fleeting situations.
It’s easy to make the mistake of shopping for optics based on price alone. After all, many scopes and binoculars on the market today appear to have similar features at extreme price differences. But once you experience the resolution and brightness of truly premium optics, you realize they’re worth the added cost. Steiner’s new Peregrine binocular is an example of a premium optic that excels optically, mechanically, and physically.
Optically, Peregrines have a very high level of light transmission afforded by 44mm Objective and 30mm Ocular (Eyepiece) lenses. Further, those lenses are fully multi-coated, as are the roof prisms. As light enters any lens, some is reflected, reducing overall light transmission. Coatings help light “ease” through a lens with less reflection, and different coatings are needed for different light waves across the visible light spectrum. Loss occurs with each air-to-glass interface, so fully multi-coated lenses are better than “multi-coated” or “fully coated,” both of which sound good but may indicate lenses with less than optimum treatment. A simple comparison test between equal size/power binoculars you can do is to block off the ocular lens while looking into the objective lens. The binocular that reflects your image the least should transmit light better.The 40+ coatings that make up Steiner’s technology used in the Peregrines allows for light transmission equally across the entire visible light spectrum. Without equal transmission, images can have color casts or are otherwise degraded. Some optics may compensate for missing parts of the light spectrum by adding color filters to “balance out” what’s missing, but filters introduce another air-to-glass interface and may reduce light transmission or provide incorrect image color.
In addition to the lens coatings, the Peregrine’s prisms receive special treatment, too. All Roof- and Porro prism-type binoculars use prisms with mirrors to “bend” the light back and forth within the optic to increase the effective length between the objective and ocular lenses. Traditionally, those mirrors are silver or aluminum, but those metals reflect only part of the visible light spectrum. To maintain the high image quality transmitted through its lenses, Steiner takes the extra step of dialectic coating its mirrors so that they, too, reflect the entire visible light spectrum. This is in addition to the phase coating normally found on better roof-prism binoculars to prevent internal reflection, or interference, at the roof-edge surface.
