refractor

An optical instrument, such as a telescope, that uses a lens to bend and focus light rays. / A device or material designed to bend light or other electromagnetic waves in a specific direction.

Danh từ

Số nhiều: refractors

This term describes a specific mechanism of light manipulation based on refraction, where light passes through a medium of different density to change direction. In astronomy, it specifically identifies telescopes that utilize a glass lens as the primary objective, distinguishing them from reflectors which use mirrors. This creates a distinct visual profile characterized by long tubes and high-contrast images.

In technical or laboratory settings, the term extends to any component designed to steer electromagnetic waves. It carries a connotation of precision and optical engineering, typically appearing in scientific discourse rather than casual conversation.
