Meaning and Definition
A telescope that uses a curved mirror to gather and focus light, rather than lenses.
An optical instrument for viewing distant objects, designed on the principle of reflection, where a primary concave mirror collects light and forms an image, which is then magnified by an eyepiece. The design avoids chromatic aberration common in refracting telescopes.
