Brand New NOVA 20x80 mm Triplet Technology (SEMI APO)Astronomical Binoculars
and Broadband Fully Multi Coated lenses and prisms.
We are offering you a 20x80 mm Triplet Technology (Semi Apochromatic) Astronomical Binoculars. Most binoculars (including similar 20x80) offer only two optical elements. This binocular has three optical elements installed and this is the only binocular in 80 mm objective lens diameter group that offers this feature. The new Triplet Objective Technology greatly improves the picture by providing a flatter Field Of View, reduces chromatic aberration and maintains sharp images at the edge of the Field Of View.
This is binocular may be used for: Astronomical Observation, Nature Viewing, Marine and Long Distance Surveillance, Targeting and Leisure Viewing.
The stabilizing bar in the middle helps the binoculars' stability and reduces the chance of miscollimation. The bar can be directly attached to a tripod so there is no need for an additional tripod adapter. This binocular comes with a central focus (SLOW FOCUS) knob and right eye diopter adjustment.
This binocular is equipped with Highest Quality High Index BaK-4 Porro Prisms for the maximum light transmissivity and reduces chromatic aberration.
The BROADBAND FULLY MULTI COATED lenses and prisms minimize internal light loss and reflection, improve image sharpness and provide the best light transmission and brightest images.
Combination of the highest quality BaK-4 prisms and Broadband Fully Multi Coated lenses will satisfy viewer's highest demand for quality optics.
The binocular is black rubber armored adding important durability. The package includes a sturdy carrying case, neck strap and lens cleaning cloth.
20x80 Triplet Objective Technology binocular offers higher value than similar standard 20x80 models.
All binoculars are inspected for collimation and mechanical work.

ADDITIONAL INFORMATION
Triplet Technology Features:
-
Triple Optical Element
-
Flat Field
-
Reduced Chromatic Aberration (False Colours)
-
Sharper image at the edge of the field of view
Prisms Info:
- High density optical glass.
- BK7 prisms are made of borosilicate high density glass
- BaK-4 high index prisms are made of much denser Barium Crown Glass that eliminates internal light scattering. This is the highest grade of prism. They are more expensive then BK7 and maintain superior sharpness on the edges in comparison to BK7 prisms.
Lens Coating types:
Fully Coated – This coating type uses Magnesium Fluoride to coat glass-to-air surfaces with the exception of prisms. This coating has one layer only and comes usually in blue lens color.
Multi Coated – This coating type is higher quality than "Fully Coated" type of coating that comes in 5-7 layers on glass-to-air surfaces and simple layer on 4 surfaces of prisms. It comes usually in the green lens color.
Broadband Fully Multi Coated – This type of coating is higher quality than similar "Multi Coated" type of coating and comes with additional multiple layers that cover all lens surfaces and prisms. It comes in the green lens color.
The better the lens coating the less reflection and light scattering. This results in higher level of light transmission and better image contrast.
