An optical bench or optical rail is a less sophisticated piece of equipment used for simple experiments, especially for classroom demonstrations.

The OLI and TIRS are mounted on an optical bench at the forward end of the spacecraft.

The vacuum chambers with optical benches range from 1 m3 to 200 m3 in volume.

The instrument consists of two parts, the telescope and the interferometer which consists of an optical bench and support electronics.

The intent of realization of the oscillator Toda at the optical bench is shown in Fig.4.

Light from the original artwork is split into separate red, blue, and green beams in the optical bench of the scanner.

The aperture is the actual opening that allows light into the optical bench of the scanner.

This usually means they have slow speed and concomitantly long exposure times, so it is necessary to ensure that the microscope is free from vibration, best done by working on a stone or concrete optical bench.

LOTIS has large, thermally stabilized vacuum chamber, vibration-isolated optical benches, and a large 6.5 meter telescope (run backwards as a collimator) to create images for the test optics to view.

In 1876, Hermann Snellen introduced a phakometer which was a similar set up to an optical bench which could measure the power and find the optical centre of a convex lens.
