I have to do an assesment of nine tasks. One of the ones I chose was to set up and use an optical flat.
Can anyone help me with that?

I went down to the Kaydon plant recently and saw how they measured their seals for the jet engines . They were measuring in "bands" , of which I didn't understand . :grin: This may be an interesting thread .

I purchased a small optical flat as a sort of self-xmas-present, having read about them in Foundations of Dimensional Metrology. Looking forward to learning how to use it when I'm next snowed in.

Is this the flat that uses a helium light?

More or less - light has to be monochromatic. Should be possible with the right LED light, still need to sort that part out.
