This iteration of the Monarch 5 features extra-low dispersion (ED) lens elements that transmit bright images with enhanced color fidelity and contrast. To preserve the image quality of these high-transmission lenses, Nikon also outfitted this Monarch 5 with phase-corrected roof prisms.

dielectric coatings, these prisms align incoming wavelengths of light and render well-defined edges with lifelike color.
