Linguistic Origin & Historical Etymology

Derived from the English verb 'reflect' (from Latin 'reflectere', meaning to bend back) combined with 'telescope', coined from the Greek 'tele' (far) and 'skopein' (to look). The design was pioneered in the 17th century by Isaac Newton to eliminate chromatic aberration found in refracting lenses.
