Next, there are three stages of grinding the lens surface as we move the lens through rough, medium and fine grinds. As with sanding a piece of wood, this process brings the surface of the glass to an increasingly finer finish. At this point the ground surface of a lens still has a smoky, translucent, rather than transparent, look

Mar 27, 2020 · Page 1 of 2 - Manually grinding a lens - posted in ATM, Optics and DIY Forum: Hello, I’ll start to grind a lens with a photographer friend who wanted after years of photography to make one himself to get a feel of the process. The first one will be made in a schott mirror blank, 102mm/15mm thick, and will be plano-convex. We don’t expect it to give diffraction limited pictures since the

Grinding papers are traditionally used for plane and fine grinding of all types of materials. Our Rhaco Grit is either based on Al 2 O 3 in the coarser grit sizes for high removal and long lifetime when grinding harder materials, or on SiC in the finer grit sizes for grinding of softer, more ductile materials
