Mirror has arrived and constructing the Foucaulttester have started

Posted on by

Now I have recieved miror and supplies from Wacuum Coatings in England. And I have started to make a Foucaulttester, it is assembled by two sledges adjusted by a screw.

The mirror and the Foucault-tester.


The mirror is a 10″ Pyrex-glas, but there is a little bubble. I think it is 1,5 mm long and is 5 mm beneath the surface. I don’t hope it will make troubles. So do an ATM from Denmark say.
