BAK-4 prism glass and fully multi-coated optics maximize transmission across the visible spectrum, delivering crisp, high-contrast images from 450 nm blue to 700 nm red.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e8× magnification, 42mm objective diameter — 5.25mm exit pupil\u003c\/li\u003e\n\u003cli\u003eBAK-4 phase-corrected roof prisms, fully multi-coated lenses\u003c\/li\u003e\n\u003cli\u003eIPX7 waterproof \u0026amp; nitrogen-purged fog-proof body\u003c\/li\u003e\n\u003cli\u003e367 ft \/ 1000 yd field of view — center focus wheel with diopter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eEvery purchase directly funds independent physics research at the Golden Physics Project.\u003c\/em\u003e\u003c\/p\u003e","brand":"Golden Physics Project","offers":[{"title":"Default Title","offer_id":54143804080420,"sku":"GPP-BINO-842","price":139.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2879\/9524\/files\/Hensoldt-Prismendoppelfernrohr.jpg?v=1780744778","url":"https:\/\/shop.goldenphysics.org\/products\/8x42-waterproof-binoculars-bak4-prism","provider":"Golden Physics Project","version":"1.0","type":"link"}
