Roof prism light path ensures optical tubes remain thin for a compact form factor Roof prism light path ensures optical tubes remain thin for a compact form factor Moderate magnification brings subjects in close without sacrificing field of view, eye relief, or exit pupil Phase-correcting prism coatings reduce internal interference to improve light transmission, contrast, and resolution Extra-low dispersion glass reduces chromatic and spherical aberrations for increased contrast, improved color rendition, and sharpness without distortion across the entire field of view
