Product Spec

FMC (Fully Multi-Coated) Coating:

FMC refers to an advanced optical treatment applied to all air-to-glass surfaces in the binocular. This multi-layer coating reduces light reflection and increases light transmission, resulting in brighter, clearer images with improved contrast and color fidelity. FMC coatings significantly enhance overall image quality and low-light performance.

By coating each air-to-glass surface, our FMC technology significantly reduces light loss due to reflection, allowing more light to reach the viewer’s eye.

BAK-4 HD Prism:

BAK-4 is a high-quality barium crown glass used in premium binocular prisms. It offers superior light transmission and a higher refractive index compared to standard BK-7 glass. BAK-4 prisms produce sharper, brighter images with better edge-to-edge clarity and improved low-light performance. They also create a rounder exit pupil for a more comfortable viewing experience.

Our BAK-4 prism uses dielectric coatings can reflect over 99% of light, significantly higher than standard aluminum coatings, results in noticeably brighter images, especially in low-light conditions. and also it provides more accurate color reproduction across the entire visible spectrum.

Lanthanum Glass:

Lanthanum glass is a specialized optical glass that contains the rare-earth element lanthanum. It has a high refractive index and low dispersion properties, which help to minimize chromatic aberration (color fringing) and spherical aberration. Binoculars using lanthanum glass elements typically offer enhanced image sharpness, improved color accuracy, and better overall optical performance, especially in challenging lighting conditions.

Lanthanide ED Glass: Reduced chromatic aberration, spherical aberration, improved light transmission, it grants exceptional brightness, great color fidelity and also maintains high performance in low light conditions.
HD Prism & Advanced FMC: Our advanced Bak-4 prism take the advantage of dielectric coating, which reflects over 99% of the light, and our advanced FMC uses broadband anti-reflection coating on every air-to-glass surface, which ensures overall light transmission 85%, brings Optimum brightness, and true color throughout the light spectrum.
Nitrogen Purged Waterproof: Usage of insert gas and O-ring structure maintains the pressure of the cavity, prevents fogging and moisturizing from inside, and the absence of oxygen helps preventing corrosion of the glass and coatings, making it suitable for extreme conditions
