Interferometry

Interferometry is a powerful tool for distance measurement, angle measurement, velocimetry and vibrometry. 

DFB and DBR lasers with its small linewidths and high frequency stability enable such interferometric measurements with high precision and superior resolution. 

Since 2013 two DFB-852 are onboard the GAIA satellite to monitor the beam angle alignment of two telescopes creating a map of billions of stars.

The lasers of our RWS laser family with integrated grating achieve nearly the same performance at lower cost.
