AR Doublet Series

Explore Scientific Explore Scientific Achromatic Doublet Series Refractors represent an excellent value in medium to large aperture refractors. A Doublet, commonly called an achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths into focus in the same plane. Unlike some competing models, these telescopes feature adjustable lens cells should the optical collimation ever need adjustment. These telescopes are best suited for deep space observing at low to medium power. Finally one can own a diffraction-limited high quality refractor for a relatively modest investment.
