Autocollimators - Spectrum Metrology

Autocollimators are used for measuring for example:

	•	Angle: (indexing head accuracy)
	•	Straightness (machine tool slides in two axes)
	•	Squareness (spindles to slideways)
	•	Parallelism (slideways)

From inexpensive visual autocollimators or dual axis digital autocollimators capable of measuring 0.01 second, equivalent to 50nm per m (or for the sportsmen and women a hole in one from London to Moscow (100mm/2000km)!

VA900 Windows ®* based software programs are available for computer processing and graphic output of flatness, straightness, squareness, twist and polygons up to 72 faces.
