The Konus Emperor Binocular was designed and built to achieve a supreme optical quality. The Emperor will leave you breathless with the impeccable brightness and clarity of their special BAK-4 prisms with phase correction. This is an advanced coating technique that will force the light beams back into phase, thus improving the image definition and contrast and creating a sharper view, especially noticeable when observing fine details.
