FAQs - Frequently Asked QuestionsWhat are the axes on the interferometer graphs?What does "spectral resolution" mean? What kind of pulsed measurement is possible and what is the accuracy? What's the difference between good and bad illumination?To ensure high accuracy of the measurements you have to adjust the optical setup well, so that the interferometers are illuminated evenly. 
Good illumination means the peaks have approx. 60 % of the screen height (at least 1000) and the height doesn't vary by a factor of more than 2. 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? |
