BelOMO (Belarusian Optical and Mechanical Assosiation) is a major opto-mechanical assembly plant of the former USSR and Belarus now. The Assosiation incorporates several enterprises which are engaged in developing and manufacturing of high-precision lasers, topographic and multispectral photographic equipment, photogrammetric systems and complexes,optoelectronic and optical and mechanical devices, medical equipment based on laser systems and different instruments and units for marine services, tourism, medicine, space.
SPECIFICATIONS
Prism binocular 7x42 is a device of wide application including solution of various combat tasks. Due to its technical specifications and ergonomics it is a reliable device for observation of remote objects with a possibility of measuring their approximate angular dimensions.
Advantages
- binocular is self-adjusting (unique optical scheme allows to have high-quality image without readjusting of oculars
- binocular is filled with dry nitrogen to avoid weeping of optical details due to sharp temperature differences
- binocular can be used in the temperature range from -50 oC to +70 oC
- binocular has rubberized case which enables to protect it from stroke (falling from the height of up to 1,8 m)
- binocular has hermetical water-proof and dust-proof case which allows to use it after immersing in water
- the great clear aperture diameter and antireflecting optics enabl_ to conduct long-term and easy observation of different objects

DESCRIPTION
This binocular is based upon the legendary UK-made Avimo military 4x42 unit, that was first introduced in year 1979 by the British optical company Avimo Optical Imaging. Throughout the 1980’s the binocular was produced on the Singapore facilities of Avimo Optical Imaging. Lately, when Avimo (that now shares different name – Thales Optics) discontinued the 4x42 model, the binocular was licensed to German manufacturer Rollei, and lately to Belarusian manufacturer Belomo.
The history of this binocular contains facts of its reliable work in the worst conditions of warfare. The binocular proved its high quality in several wars that British army took part in. First tested in painful Falkland’s campaign, Avimo 7x42 was used decades later in wars in Iraq and Afghanistan by Her Majesty military troops.
The baptism of fire of this binocular took place more than thirty years ago. As Argentina forced Great Britain to defend their overseas territories in Falkland’s war in 1982, this 7x42 binocular was tested in rough conditions of sub-Antarctic battlefield scenes. Though British troops found the design with raised binocular tubes not to be the most comfortable in combat conditions, this particular optical device had shown its durability and almost bullet-proof quality.
Prism 7x42 binocular is waterproof, has clear visibility in the twilight, it’s self-adjusting (that means you don’t have to adjust it every time you want to look at a closer or more distant object), has coated optics (which allows long and convenient observation of objects). Since its inner cavities are filled with nitrogen, there’s no fogging when temperature drops. This binocular is quite comfortable, rubberized casing allows you to securely hold binoculars in hand even in the rainiest and the most wet weather conditions, as well protects the unit against the impacts.
As mentioned before, the model that is the basis for BelOmo Military Prism Binocular 7x42 is in use form 1980’s till the present day. This prism design binocular sustained different climatic conditions from rough Antarctic polar snow storms and freeze to desert dusty storms and sizzling heat.
