HR ED Fieldscopes
HR 66 GA ED, HR 80 GA ED
“Smaller, lighter, brighter, sharper” Opticron HR ED fieldscopes are designed and manufactured to deliver exceptional optical performance combined with sublime handling and total reliability.
Aimed squarely at the serious user, HR ED fieldscopes are built to withstand extremes in temperature, to operate unaffected by rain, cold or humidity and be used anywhere from the equatorial rainforests to the poles. Delivering the highest resolution figures in the Opticron range, each model contains a high definition 5 element apochromat objective lens with 2 individual ED elements. In addition to enhancing resolution, this second element delivers significant reductions in chromatic aberration compared to single element designs.
To optimise light transmission and colour contrast across the magnification range, Opticron N-type extra wide band multi-coating is applied to all air/glass surfaces throughout each instrument. Mechanically HR ED fieldscopes feature a magnesium alloy body fitted with a +/- 90° rotating tripod sleeve. Fully nitrogen gas filled waterproof and hermetically sealed against penetration from dust and moisture, the models are protected in durable textured rubber armour. Other features include a centrally positioned focus wheel for optimum accessibility, retractable lens hood (sunshade) and integrated rubber objective lens cover.
