Etalons, tuneable
Fabry Perot etalons can be tuned with respect to their spectral properties by varying the resonator length.
By using piezo-active structures an active resonator control and long-term stabilization can be achieved (eg. piezo actuated mirror mounts for tilt correction of the end mirrors or ring actuators for tuning the resonator length).
A high precision wide range adjust can be done by using the SVR amplifiers providing an additional 30% yield in stroke due to the semi-bipolar output voltage (compared to conventional uni-polar systems).
