FAQs - Frequently Asked QuestionsWhat are the axes on the interferometer graphs?What does "spectral resolution" mean?The spectral resolution is the distance between 2 (laser-)modes you can seperate in the fizeau-interferogramm. For example, a laser has got a small sidemode beside the main peak. On the interferometer-picture you only can see this sidemode if it has got a certain distance to the main peak, e.g. > 10 GHz. This value, 10 GHz, has nothing to do with the accuracy.  What kind of pulsed measurement is possible and what is the accuracy? What's the difference between good and bad illumination? Ltr-files - Why? How to generate an ltr-file? The Multichannel-Switcher shows the same picture on all channels What about the temperature stability of the wlm? What is the TTL-synchronization option for? Why is the (re-)calibration of wlm that important? How to find the best parameters for the PID-controller? |
