Product Description:

BAK4 has a high refractive index and lower critical angle than other materials, which means it transmits light better with less light being lost due to internal reflection such as from internal bubbles trapped during the manufacturing process.

Fully Multi-coated Glass means multiple coatings on all lens surfaces. And all air-to-glass surfaces are anti-reflective multi-layer coated. And fully multi-coated objective lens increases the light transmission, delivers bright, clears and crisps images even in low-light conditions.

The optical structure uses a 3-piece objective lens, a focusing lens, a set of high-precision roof prisms, and a 4-piece 3-group eyepiece. Usually, the objective lens of binoculars is two-piece, and this three-piece type can reduce the aberrationand improve the image quality better.

Wide angle large field of vision, comfortable and long eye relief, humanized observation experience.

Multiple gears and twist-up eyecups are suitable for people with different visions, and myopic users do not need toremove glasses to enjoy easy observations. So whether you wear glasses or not, you can find the comfortableobservation position by adjusting the eyecups.
