The Levenhuk Bruno Plus 25×100 binoculars are a powerful optical instrument designed for challenging observations of distant objects on Earth and in the night sky. With their high 25× magnification, they allow for detailed observation of landscapes, distant animals, or astronomical objects such as lunar craters, star clusters, or brighter nebulae. The large 100mm objective lenses ensure high brightness and a clear image even in low light conditions. The optical design uses BaK-4 glass Porro prisms and multi-coated anti-reflection layers on all optical elements, which increases light transmission and improves image contrast. The robust aluminium alloy body with a rubberised surface provides high mechanical resistance and a secure grip even in demanding conditions. Additionally, the Levenhuk Bruno Plus 25×100 binoculars are fully sealed, nitrogen-filled, and meet the IP67 protection standard, meaning they are protected against dust, rain, and short-term immersion in water.

The Levenhuk Bruno Plus 25×100 binoculars use an optical system with BaK-4 glass Porro prisms, which provide a bright image with high contrast and good depth of field. The large 100mm objective lenses capture a large amount of light, which is advantageous for observing at dusk or during astronomical observations. Multi-coated anti-reflection layers on all optical elements increase light transmission and reduce unwanted reflections. A resolution of up to 2.5 arcseconds allows for the observation of fine details on distant objects. The binoculars thus offer a high-quality image across the entire field of view.

The body of the Levenhuk Bruno Plus 25×100 binoculars is made from a strong aluminium alloy and is coated with a protective rubber layer, which improves grip and protects the instrument from impacts. The construction is hermetically sealed and filled with nitrogen, which prevents the optics from fogging up during rapid temperature changes. The instrument meets the IP67 protection standard, so it is fully protected against dust and can withstand short-term immersion in water. Thanks to its robust construction, it is suitable for use in the field and in adverse weather. The rubberised surface also allows for a secure hold, even when wearing gloves.


The Levenhuk Bruno Plus 25×100 binoculars are equipped with a central focusing wheel with smooth operation for quick and precise sharpness adjustment. A dioptre correction of ±4 dioptres and an adjustable interpupillary distance from 53–74mm allow for customisation for different users. Twist-up eyecups with three fixed positions increase comfort during long-term observation. At high magnification, it is advisable to use a tripod for a stable image, which can be attached using the standard 1/4” thread and the metal adapter included in the package. The set also includes a protective pouch, a strap, lens and eyepiece caps, and a cleaning cloth for maintaining the optics.
