    "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 built 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.



    The Kowa Genesis features C³ multicoatings, which are designed to deliver optical images with precise colour definition.


    Kowa: Fluorite Crystal in Optics

    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-8544/KWA10544 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. All lenses contain environmentally friendly Eco-Glass that does not contain lead or other harmful substances.
