Hi everyone, I'm building a white light interferometer and need help choosing and finding a white light source. I'm using this mirau objective: http://www.edmundoptics.com/microsc...ectives/nikon-interferometry-objectives/59312 Here is the setup: I know that the light source will have to be collimated and go through an aperture stop, field stop, bandpass, etc. I was hoping that there was a white light laser that does these steps already so that I don't have to work with several different lenses and build a setup for them. Such a laser must exist, no? Does anyone know where I can find one? Ideally one that is 100-200 Watts? I've looked all over but am having trouble finding an manufacturer that makes what I'm looking for. Are there any important steps that I'm missing? Should a collimated white light beam do the job? THANKS!
