High-performance glass material

Thanks to the premium ED (Extra Low Dispersion) glass, the binoculars produce brilliant, true-colour images in stunning colours. The ED glass significantly reduces scattered light and prevents chromatic aberration. It also increases the light transmission and allows you to observe the surroundings in high resolution and stunning detail.

Premium coatings

All optical components in the ALPEN  OPTICS Rainier HD binoculars feature ALPEN's exclusive UBX multi-layer coating to ensure maximum light transmission. Thanks to the more than 60 layers of our SHR metallic and PXA phase coating on the extra-large BaK-4 prisms, images are rendered with exceptional sharpness, contrast and colour fidelity.

Durable and weatherproof design

The durable ALPEN  OPTICS Rainier 10x42 HD binoculars come with a rubber armouring and are ideal for hunting and other outdoor activities - even in adverse weather. The waterproof magnesium housing protects the optics from rain, fog, snow and other environmental influences. In addition, the binoculars are filled with nitrogen to prevent the lenses from steaming up on the inside.

Perfect for spectacle wearers

The ALPEN OPTICS Rainier binoculars are equipped with twist-up eyecups to ensure maximum viewing comfort for people who wear glasses. Simply fold over the eyecups to obtain the perfect distance between your eyes and the eyepieces lenses. Thanks to the LE (long eye relief) eyepieces, you will be able to see the entire field of view. The binoculars are also equipped with an A-lock dioptre system, which locks your settings in place to ensure that the optics stay perfectly adjusted to your vision.

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.

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.

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.

Watertight design

Thanks to the waterproof housing that prevents liquids from reaching the inside of the optics, you don’t need to worry about heavy rain or dropping the binoculars in a puddle.

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.

Sturdy, lightweight design

Explore your surroundings without carrying heavy equipment – the premium optics are enclosed by a magnesium housing, which keeps the weight to a minimum and provides optimal protection thanks to its robust properties. Perfect for outdoor adventures!

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.

Dioptre adjustment with lock function

Thanks to the A-lock dioptre adjustment, you can quickly adjust for differences in vision between your eyes. There is also a convenient built-in lock, which locks your setting in place so that you don’t have to readjust the optics when you reach your next observation spot.

Water-repellent coating for unobstructed view

Thanks to the exclusive ALPEN LPE water-repellent lens coating, water drips off the lenses just like a lotus flower! This ensures that dirt is washed away during rainy weather to give you an unobstructed field of view.

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.
