Squareness measurement kit
This kit allows the measurement of axis squareness (perpendicularity). It must
be used in conjunction with the straightness measurement optics and also, when
one axis is vertical, the adjustable turning mirror, straightness shutter and large
retroreflector .
Large retroreflector
The large retro-reflector is used to measure the
straightness of vertical axes. It can also be used
in certain horizontal straightness configurations
where it is not possible to place the stationary
straightness reflector behind the interferometer.
Straightness shutter
The straightness shutter has two rotational
elements allowing for compatibility with the
straightness measurement optics in both
horizontal and vertical orientations.
