Laser calibration system for CNC, CMM and measuring machines
ISO230-2, VDI/DGQ 3441, NMTBA, BIS BS 4656 part 16 | µLine Status Pro GmbH

Status Pro offers Equipment, Training und Support for the measurement,
calibration and compensation of machine geometry.

µLine has a very extensive "weather station" environmental influences on the measurement are kept to a strict minimum through comprehensive temperature and pressure compensation.

µLine was developed for the industrial rather than the lab environment. It's a two laser frequency interferometer with an integrated PSD for laser position detection.

Therefore not only does it provide extremenly precise length / distance measurement but also straightness measurement in X and Y. The first stage interferometer prism is kept out of the laser housing to avoid thermal influences and offer maximum flexibility in the setup.
This is often critical in production line applications because it minimizes the degree of machine disassembly required.

Advantages of Interferometers:

<µm precision in Distance measurement
Extensive environmental compensation
X,Y and Z measurement simultaneously
Support of machine compensation norm and procedure
