Nikon 16X32 Stabileyes RECOMMENDED FOR: Astronomy Body This full-size binocular weighs g. Roof prism designs have straight barrels with the front objective in-line with the eye piece. This design architecture makes it possible to produce more compact binoculars than porro or inverted porro designs. Optical consequences of the design are that roof prisms are more expensive to manufacture than porro binoculars of the same quality and require phase distortion coatings to eliminate the reduced contrast and sharpness caused by phase distortion ?¿¿ a roof prism phenomenon.?¿ Roof prisms also produce a more photographically normal depth perception than porro prisms because the lens barrels are in line with the eyepieces. Coating Rating Coatings help improve light transmission, especially in roof prism designs. This binocular is rated as FULLY MULTI-COATED, meaning that all surfaces have more than one coating. Special Coatings Phase Correction Coating Corrects phase shifts caused when light reflects off the roof prism. It provides a high-contrast image by eliminating the reduction of resolution. Eye Relief The 15mm eye relief on this binocular provides superb viewing comfort for both spectacle and non-spectacle wearers. Exit Pupil This binocular has an exit pupil of 2.0mm, suitable for use in bright and light overcast daylight conditions.
