Oct 17, 2011 · Yes and no. You can machine glass with the tools you have. You can grind your own lenses. What you can't do, or can't do easily, is to mill from block of glass to polish ready lens without making a grinding tool. The words polish and grind are not used the same by lens makers as we use them. In the above I used the machinist definitions.

Optical lens tissue and alcohol should be used to clean optical flats. Since the measurement resolution of an optical flat is a light band (.0000116" or .295 micron), components must be flatter than 15 or 20 light bands in order for the optical flat to be able to make the interference fringes visible.
