The Kowa Prominar 8x42 DCF ED Binoculars is a step-up from Kowa's previous BD range with a wider field of view of approprimately 20% and a new stylish and ergonomic body which boasts efficiency and visual appeal. It also incorporates Kowa's fine Prominar XD lens design with 2 sets of XD lens which eliminates chromatic aberration and enables a high contrast viewing experience, all encased within a light weight yet rugged magnesium alloy body that ensures that we get top optical performance in most severe weather conditions.

"PROMINAR" XD Lenses

The "PROMINAR" XD Lenses combined with a concave lens possessing special dispersion properties dramatically reduces the possibility of chromatic aberration. This ensures that discolouration, graininess or blurriness is an issue of the past! The lens are also coated with C3 coating which is build to enhance the prism reflection rate. Ultimately this technology optimises the amount of light gathered so that you attain a brighter and clearer field of view.

Multi-coating

All lenses have multilayer coating so you that you attain a wider field of view

Features:

  • Waterproof / Fog-proof
  • 8x Magnification
  • Magnesium Alloy
  • 10 Year Warranty
  • Fully Multi Coated
  • Nitrogen Filled

  Lens

One of the major causes of deterioration of viewing quality in optics is chromatic aberration (colour blur). Chromatic aberration occurs due to the dispersion of light and the different wavelengths of light focusing on different positions, resulting in a red or purple fringing around the image. The optimum optical material to minimise chromatic aberration is fluorite crystal.

A fluorite crystal with extremely low dispersion characteristics is used for the convex lens of the KWA-PRO842/KWA-PRO1042 PROMINAR models. In place of an ordinary optical glass lens, the concave lens paired with the fluorite crystal lens is made of glass with special dispersion properties to reduce the chromatic aberration to a further degree.

This combination of fluorite crystal and glass with special dispersion properties nearly eliminates chromatic aberration and redefines the standards of colour brilliance.

This technology is the result of many years of optical design and has realised great reduction in chromatic aberration, while maintaining a large diameter lens and high contrast images when compared with conventional models.

The XD lens used in the KWA-PRO842/KWA-PRO1042 PROMINAR models has characteristics similar to those of fluorite crystal to significantly reduce the chromatic aberration. All lenses are environmentally friendly Eco-Glass. (Eco-Glass is an environmentally friendly glass that does not contain lead or other harmful substances.)
