The game gets on its feet. Bright binoculars are the most important tool for hunting in twilight or in darkness. If maximum image brightness is what you are looking for, the Abbe-Koenig prism is the best choice. Why? This system makes it possible to reverse the image without any loss of light, as the surfaces do not need to be mirrored. The result is a uniformly bright, high-resolution image that really shows off its strengths in adverse lighting conditions.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"708\" height=\"474\" src=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/Abbe_K\u00f6nig_Prisma_white.jpg\" alt=\"\" class=\"wp-image-3686\" srcset=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/Abbe_K\u00f6nig_Prisma_white.jpg 708w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/Abbe_K\u00f6nig_Prisma_white-600x402.jpg 600w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/Abbe_K\u00f6nig_Prisma_white-640x428.jpg 640w\" sizes=\"auto, (max-width: 639px) 98vw, (max-width: 1199px) 64vw, 708px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Extremely high light transmission and image brightness <\/h2>\n\n\n\n<p>The history of roof prisms goes back to the Italian Giovanni Battista Amici around 1843. As the name \u201croof\u201d suggests, the path of the beam passing through the Amici prism has a shape that resembles the roof of a house. Before the turn of the century, the physicist Ernst Abbe modified the Amici prism into a straight roof prism. Around 1900, Albert K\u00f6nig completed development by separating the two prisms with an air gap \u2013 a milestone in the history of optics development. This improved straight prism system is known as the Abbe-Koenig prism and was protected by ZEISS&#8217; trademark from July 7, 1901 onward. Beginning in 1911, the ZEISS factory in Jena produced the first straight binoculars with Abbe-Koenig roof prisms.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Unsurpassed hunting experiences even as daylight begins to fade<\/h2>\n\n\n\n<p> Roof prism binoculars have numerous advantages. On the one hand, they offer extremely high light transmission, which makes them ideal for twilight and night hunting because of longer observation times and more accurate identification.  <\/p>\n\n\n\n<figure class=\"wp-block-gallery columns-2 is-cropped wp-block-gallery-1\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"886\" height=\"591\" src=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_dunkler.jpg\" alt=\"\" data-id=\"3328\" data-full-url=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_dunkler.jpg\" data-link=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/zeiss-t-coating\/zeiss-demo_ht_dunkler\/\" class=\"wp-image-3328\" srcset=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_dunkler.jpg 886w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_dunkler-600x400.jpg 600w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_dunkler-768x512.jpg 768w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_dunkler-640x427.jpg 640w\" sizes=\"auto, (max-width: 639px) 98vw, (max-width: 1199px) 64vw, 770px\" \/><figcaption class=\"blocks-gallery-item__caption\"> Standard Glass<\/figcaption><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"886\" height=\"591\" src=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_heller.jpg\" alt=\"\" data-id=\"3329\" data-full-url=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_heller.jpg\" data-link=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/zeiss-t-coating\/zeiss-demo_ht_heller\/\" class=\"wp-image-3329\" srcset=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_heller.jpg 886w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_heller-600x400.jpg 600w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_heller-768x512.jpg 768w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/07\/ZEISS-Demo_HT_heller-640x427.jpg 640w\" sizes=\"auto, (max-width: 639px) 98vw, (max-width: 1199px) 64vw, 770px\" \/><figcaption class=\"blocks-gallery-item__caption\"> SCHOTT HT Glass<\/figcaption><\/figure><\/li><\/ul><figcaption class=\"blocks-gallery-caption is-layout-flex wp-block-gallery-is-layout-flex\"><em>SCHOTT high-transmission glasses for optimum identification and resolution of targets in the  twilight hours and at night.<\/em><\/figcaption><\/figure>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">ZEISS\u00a0Victory\u00a0HT series<\/h2>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-1 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p>The ZEISS\u00a0Victory\u00a0HT series is a prime example of outstanding optical performance. They are particularly robust and withstand even adverse weather conditions. Internal focusing makes them dustproof and waterproof. Thanks to the rubber or plastic coating, they are easy to grip and offer excellent shock absorption. Most of the housings are made of high-strength magnesium and are therefore lightweight, which makes many hours of fatigue-free observation possible. Compared to the wider Porro binoculars, roof prism binoculars are characterized by a slim, aesthetic design. And thanks to their compact and lightweight design, they are also very practical and easy to transport.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"808\" height=\"1024\" src=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/victory-ht-sectional-view-808x1024.jpg\" alt=\"\" class=\"wp-image-3701\" srcset=\"https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/victory-ht-sectional-view-808x1024.jpg 808w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/victory-ht-sectional-view-474x600.jpg 474w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/victory-ht-sectional-view-768x973.jpg 768w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/victory-ht-sectional-view-1213x1536.jpg 1213w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/victory-ht-sectional-view-640x811.jpg 640w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/victory-ht-sectional-view-1024x1297.jpg 1024w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/victory-ht-sectional-view-1200x1520.jpg 1200w, https:\/\/blogs.zeiss.com\/sports-optics\/hunting\/en\/wp-content\/uploads\/sites\/2\/2020\/08\/victory-ht-sectional-view.jpg 1579w\" sizes=\"auto, (max-width: 639px) 98vw, (max-width: 1199px) 64vw, 770px\" \/><\/figure>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>If maximum brightness is what you are looking for, the Abbe-Koenig prism is the best choice.
