By using interferometry, the wavelengths of a laser along a path alongside a body are counted and interpolated, which makes an unusually large measuring range possible, from several dozen metres to fractions of nanometres. |
|
The XL-80 is quick and easy to set-up and use, reducing waiting time and increasing available measurement time, whilst still retaining the accuracy benefits of a pure interferometry based system. |
