Leica 10×40 Trinovid Classic Binoculars

Description

The Leica 10×40 Trinovid Classic Binoculars are a full-size heritage roof prism optic built for traditional wildlife observation and open-country scanning. Combining 10x magnification with 40mm objective lenses, this streamlined instrument delivers a 313.25-foot linear field of view at 1000 yards (104m at 1000m), an actual angle of view of 6.0 degrees, a 4mm exit pupil, and 16mm of eye relief for steady handheld observation and reliable target resolution across agricultural plains, forest edges, and alpine hillsides.

The optical system incorporates an Uppendahl roof prism design that maintains a slim, straight-barrel profile without unnecessary optical bulk, paired with fully multi-coated optical glass surfaces that optimize color saturation and light transmission. Machined from high-strength aluminum alloy finished in textured black leatherette armoring, the housing measures 14.2 by 11.2 by 5.3cm (5.59 x 4.41 x 2.09 inches) and weighs 640g (22.58 oz). The chassis is splashproof and weather-resistant against light rain and dust. Adjustments center on a smooth central focusing wheel with an 18.04-foot (5.5m) close focus distance, a central bridge diopter adjustment dial spanning -3 to +3, retractable rubber eyecups, and an interpupillary distance range from 55mm to 75mm.

Uppendahl Roof Prisms & High-Contrast Multi-Coated Optics

The Uppendahl roof prism layout aligns optical light paths in a compact straight line, minimizing barrel diameter while maintaining balanced optical throughput. Multi-layer anti-reflective coatings applied to each air-to-glass boundary suppress internal flare and surface reflections, preserving high optical contrast when glassing backlit forest edges or open hilltops. The 4mm exit pupil provides comfortable image brightness during bright daylight and shaded woodland excursions.

Classic Aluminum Chassis & Central Focusing Bridge

The rigid aluminum alloy body provides durable protection for internal lens groupings while keeping total carry weight to 640g for fatigue-free all-day field transport. The textured black leatherette cladding offers a comfortable, secure hold in temperate weather conditions. The central focusing wheel rotates with fluid mechanical resistance, complemented by a central bridge-mounted diopter adjustment ring that locks individual eye balance for dependable optical alignment across diverse viewing distances.

• Central focus mechanism with bridge-mounted diopter ring providing precise focal balancing
• Durable aluminum alloy body finished in classic textured leatherette for refined handling comfort
• Retractable rubber eyecups providing comfortable eye placement and full visual field access
