Rails and Benches
An optical bench or optical rail is a less sophisticated piece of equipment used for simple experiments, especially for classroom demonstrations. It is a long, straight, sturdy rail of steel onto which components such as light sources and lenses can be bolted down and easily shifted along the length of the rail.

Famous quotes containing the words rails and/or benches:
“You could almost see the brass on her gleaming,
Not quite. The mist was to light what red
Is to fire. And her mainmast tapered to nothing,
Without teetering a millimeter’s measure.
The beads on her rails seemed to grasp at transparence.”
—Wallace Stevens (1879–1955)
“And now on benches all are sat
In the cool air to sit and chat,
Till Phoebus, dipping in the West,
Shall lead the world the way to rest.”
—Charles Cotton (1630–1687)
