Smaller, lighter and sharper, the Opticron HR 66 ED fieldscopes offer a host of improvements over preceding models and have been redesigned without compromise in order to deliver truly exceptional optical performance combined with sublime handling and complete reliability.
Aimed squarely at the serious fieldscope user, the models are built to withstand extremes in temperature, to operate unaffected by rain, cold or humidity and as such can be used anywhere from 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, Opticron 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. Opticron HR ED fieldscopes are supplied with a comprehensive 30 year guarantee.
