The Explore Scientific are optimized to produce high contrast, high resolution and superior flat field characteristics. It is waterproof and nitrogen-purged, to ensure that the internal elements remain clean and dry. All internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves, the fully multi-coated to minimize the scattering of light within the lenses. It provides a huge field-of-view and long eye relief by using advanced computer design, combinations of low dispersion and high refractive index optical glasses. Precision machined metal lens barrels that maintain the perfect alignment of the optical train for years of rugged use in the field.
