FAQs - Frequently Asked Questions
What are the axes on the interferometer graphs?
The horizontal (x) axis of the graph represents the chip number of the ccd line-array. The vertical (y) axis is the
voltage of every single chip in mV. The graph therefore is the direct reproduction of the interferences pattern focussed
on the array. It is not the spectrum! But you the get some spectral information of a interferometer, e.g. if your laser
is running single mode or if it has got sidebands (see next question) 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?
Ltr-files - Why?
