Roof prisms — also called straight view binoculars, permit a slender design. Due to the prism alignment, eyepiece and lens are arranged in one line (straight view). NOBLEX binoculars are equipped with different focussing versions. The range comprises models with central focussing (CF) or individual focussing (IF).The use of NOBLEX lenses guarantees a true to original color reproduction and an increased sense of contrast. The picture seems clearer, more focussed and spatial. Special lenses reduce the color fringes, thus guaranteeing a high degree of detail perceptibility. NOBLEX binoculars have a large eye relief distance, which makes them particularly suitable for spectacle wearers. The entire field of view is available to spectacle wearers. The individual binocular-eyedistances can be adjusted, either by turning over the rubber eye cups or by twisting the "twist up" eyepieces in three latching steps.
