Injecting nitrogen into the telescope's sealed barrel can effectively prevent moisture from entering, waterproof and anti-fog, and can be used normally even in very harsh environments, greatly improving the service life.

Fully Multi-coated Lens

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 lensincreases 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 the three-piece type can reduce the aberration and improve the image quality, but the cost is also higher.
