Eschenbach Optik 8×42 Trophy D-Series ED Binoculars

Description

Track swift woodland wildlife across expansive viewing perimeters through the Eschenbach Optik 8×42 Trophy D-Series ED Binoculars high-performance roof prism optical system. Pairing an optimal 8x magnification with 42mm objective apertures, this German-engineered field instrument provides a wide 404.2-foot linear field of view at 1000 yards (134.7m at 1000m), an actual angle of view of 7.7 degrees, an accommodating 5.3mm exit pupil, and 11mm of eye relief for rapid target location and comfortable scanning during nature walks and hunting expeditions.

The optical system features BaK-4 roof prisms treated with phase-correction coatings and dielectric mirror depositions, paired with special extra-low dispersion (ED) optical glass elements and broadband high-transmission multi-coatings. Built inside a rugged magnalium (magnesium-aluminum alloy) chassis encased in black protective rubber armoring, the binocular measures 14.3 by 12.5 by 5.8cm (5.6 x 4.9 x 2.3 Inches) and weighs 785g (27.69 oz). The internal barrels are dry nitrogen gas filled and O-ring sealed for complete waterproof and fogproof protection. Mechanical controls center on high-quality metal adjustment wheels including a central focus drum with an 8.2-foot (2.5m) close focus distance, a right-eye diopter adjustment ring, retractable spectacle eyecups, an interpupillary distance range from 54mm to 74mm, and a stable 1/4-20 threaded tripod adapter socket.

Key Features of Eschenbach Optik 8×42 Trophy D-Series ED Binoculars

Engineered for wildlife observation and outdoor exploration, this 8×42 roof prism binocular combines extra-low dispersion ED glass with dielectric-coated BaK-4 prisms. Its wide 7.7-degree actual field of view delivers broad panoramic visibility across moving subjects. The nitrogen-sealed magnalium alloy chassis, metal mechanical adjustment wheels, and multi-coated optics provide reliable durability and image contrast in all weather conditions.

Dielectric-Coated BaK-4 Prisms & Extra-Low Dispersion ED Glass

The optical system integrates extra-low dispersion ED glass elements to eliminate secondary chromatic aberration, preventing color fringing around high-contrast target silhouettes. Phase-corrected BaK-4 roof prisms treated with dielectric mirror coatings maximize light reflection efficiency, preserving authentic color balance and high image brilliance across changing daylight conditions. Broadband high-transmission multi-coatings minimize internal reflections, providing sharp edge-to-edge resolution when scanning dense brush or open fields.

Magnalium Alloy Housing & Metal Mechanical Adjustment Wheels

The impact-resistant magnalium chassis delivers structural durability to protect internal optical alignments from mechanical shocks while maintaining a balanced weight in the hands. High-quality metal focusing wheels and diopter rings rotate with precise tactile resistance, allowing smooth, micro-fine focal adjustments in cold weather. Dry nitrogen gas filling prevents internal optical fogging during abrupt temperature changes, while the rubber armoring provides a secure, non-slip grip in wet conditions.

• High-quality metal central focus wheel and diopter ring offering durable mechanical control
• Watertight nitrogen-purged magnalium alloy housing built to withstand rough outdoor handling
• Retractable spectacle eyecups maintaining comfortable eye alignment for all observers
