Crystal-clear images with premium quality optics

Unlike the standard BK-7, the optics are made from BaK-4 glass (barium crown glass) that produces even sharper and brighter images. The high-quality BaK-4 glass optics are used in all ALPEN Optics products sold in Europe.
Symbol for fully multi-coated lenses for enhanced light transmission

More light for clearer images

The optics are fully coated with a premium multi-layer coating, which increases the light transmission to up to 95% to produce stunningly bright images.
Fogproof symbol indicating sealed and nitrogen-purged optics

Weatherproof design

The binoculars are filled with nitrogen, which prevents the inside of the lenses from fogging up and obstructing your view during abrupt changes in temperature.

Waterproof design

The housing features a splashproof design, which protects the optics during rain and adverse weather.

Easily adjustable for glasses wearers

Thanks to the twist-up eyecups, the design is also suitable for people who wear glasses. The distance between your eyes and the lenses can be easily adjusted to allow you to see the complete field of view.

Fine tune to your vision

The built-in dioptre adjustment allows you to quickly adjust the optics to your vision and compensate for differences between your left and right eyes.

Tripod connection thread

Thanks to the tripod connection thread, the optics can be quickly mounted on a tripod so that you can enjoy shake-free images of animals or nature.

Precise rangefinder

Know how close you are to your target – the built-in rangefinder measures the distance to animals, buildings and other objects with precision, up to range of 2286 metres.

Brighter images

The ultra-bright coating lets even more light into your eyes so that you won’t be left in the dark during twilight and in challenging light conditions.

Nitrogen filling

The temperature can change rapidly when you’re out in the wild. To prevent the lenses from fogging up on the inside and obstructing your view, the optics are filled with nitrogen.

Stunning true-colour images

The high-performance ED glass significantly reduces scattered light and prevents chromatic aberration, enabling you to observe true-colour, brilliant images of wild animals, landscapes and more.
