The new Seagull ED has it all: ED optics, phase coating, new multi-coatings and a sleek appearance. The ED lenses and Phase coating on the prisms guarantee sharp, clear and contrast-rich colors without color errors. The Seagull ED is also equipped with high-quality multi-coatings. These multi-coatings ensure that you experience the colors as they are: naturally and with great detail. In addition, all this technology is contained in a robust, light-alloy housing.
This advanced, expensive coating can only be found with the very best roof prism viewers from Bynolyt. In a roof prism a phase shift occurs between light beams, which are mirrored from the different prism planes. This has the consequence that a point is not depicted as a point, but as a spot. That gives sharpness and brightness loss. Phase correction coatings eliminate that phase difference, so that the viewer image becomes razor sharp and crystal clear.
