Leica 10×25 BC Trinovid Binoculars
Inspired by their iconic full-sized counterpart, the Leica 10×25 BC Trinovid Binoculars delivers the performance users have come to expect from the brand, but in a highly portable and easy-to-carry design. The Leica 10×25 BC Trinovid is designed with a combination of phase-corrected BAK4 roof prisms, the proprietary HighLux system, and HDC fully multi-coated optics to produce bright and clear color-neutral images, while fitting comfortably in the hand for long, fatigue-free glassing sessions.
The HDC coatings on the Leica 10×25 BC Trinovid add abrasion-resistance to protect the exterior lens surfaces, and the lenses are also treated with AquaDura coatings which make it easy to clean dirt, grime, oils, sap, and fingerprints without leaving residues that can interfere with views.
Designed to easily fit in a pocket, pack, or purse, the Leica 10×25 BC Trinovid is made with a dual-hinge system that allows the optical tubes to fold and tuck under the closed bridge to ensure the smallest form factor when fully closed. This also provides a wide interpupillary distance adjustment for easier use by those with narrow faces — like children and adolescents.
Helping to reduce the weight to a mere 9 ounces is an aluminum alloy chassis that is wrapped in a protective slip-resistant armor for a more comfortable feel in the hand. Light, compact, and easy-to-use while delivering bright and clear images, the Trinovid BCA is made to be your constant companion on the trail, at the stadium, or sightseeing around the world.
Optical Performance
- Powerful 10x magnification allows for detailed observations of distant subjects
- Compact 25mm objective lenses ensure slim optical tubes to maintain a compact form
- BAK4 roof prisms deliver a round exit pupil, and a crisp and clear image with limited edge distortion
- P40 phase-correcting prism coatings increase light transmission while improving contrast and clarity
- HDC fully multi-coated system has abrasion-resistant and anti-reflection properties to protect exterior lens surfaces, and improve light transmission and contrast
- HighLux-System (HLS) maximizes light throughput to improve color rendition and contrast
- Hydrophobic AquaDura coating on external optical surfaces allows dirt, dust, and fingerprints to be removed easily
