A device used to accelerate the electrons in a free-electron laser by channeling microwave energy into waveguide cavity assemblies.

A double meniscus system in which two achromatized meniscus lenses are arranged symmetrically on either side of the aperture stop, reducing or eliminating distortion, coma and lateral color.

Straight line travel. This denotes the fact that light travels in a straight line when traveling through a medium with a constant refractive index.

The scanning of a region in a given sequence of slender, straight parallel strips.

An optical system that is corrected for distortion and spherical aberration and therefore forms the image of a straight line as a straight line.

The pattern of lines traced by rectilinear scanning in display systems.
