The viewfinder is slightly smaller to accommodate the large parabolic reflector.

"The large reflector is just about ready," Rudy said.

All the heliostat mirrors send accurately parallel beams of light into a large paraboloidal reflector which brings them to a precise focus.

With larger reflectors, the Type 273 also served well as air-warning against low-flying aircraft, with a range up to 30 miles.

The segments can be either spherical or asymmetric (if they are part of a larger parabolic reflector).

Someone else had a larger reflector still.

The Dungeness mirrors, known colloquially as the "listening ears", consist of three large concrete reflectors built in the 1920s-1930s.

For a given size of light source, a larger reflector allows a tighter beam to be produced.

Each burner had a large and suitable reflector.

A tuner is a construction with large metallic reflectors that can be moved to different orientations in order to achieve different boundary conditions.
