BK-7 feature
BK-7
BK-7 are prisms made of Borosilicate Crown glass, commonly used in binoculars, telescopes and other optical devices. This glass is characterized by good optical properties and an adequate refractive index, which makes it possible to achieve decent image quality at a favorable price. BK-7 prisms provide sufficient brightness and sharpness for standard applications, making them a popular choice in consumer-grade optical equipment.
Central Focus feature
Central Focus
Central Focus System is a mechanism used in binoculars that allows simultaneous focusing for both eyepieces using one centrally located knob, easy and quick to operate.
FC - Fully Coated feature
FC - Fully Coated
FC (Fully Coated) is a technology used in optics to apply a single layer of anti-reflective coating to all lenses in contact with air. The purpose of this coating is to reduce reflections and increase light transmission, resulting in a brighter, clearer image. Fully Coated provides a noticeable improvement in image quality over uncoated optics and is a good compromise between price and performance.
