The shear Plate interferometer is an extremely simple means to observe interference and to use this phenomenon to test the collimation of light beams, especially from laser sources which have a coherence length which is usually a lot longer than the thickness of the shear plate (see graphics) so that the basic condition for interference is fulfilled.

The Centering Microscopes are designed for job set-up and inspection with vertical milling machines, large jig borers, boring mills, lathes, electrical discharge machines, tape-controlled machines, drill presses.

Bow gauge is a three-point contact gage equipped with a dial indicator or digital micrometre. The gages feature a protruding plunger which measures the peak-to-valley depth of the surface.
