Optical Benches An optical bench is a support for optical parts comprising a solid bed that permits precise longitudinal movement of one component relative to the others, and a number of sliders equipped with holders for lenses, lamps, apertures, eyepieces, ground glass, etc. Scales often are provided to measure the movement of the various sliders. Some special-purpose benches carry a nodal slide and flat-field bar with a microscope carriage for lens testing. Two-dimensional benches have appeared recently that consist of a surface plate rather than a longitudinal track.
