Once ground, the surfaces are transferred to automated or manual pitch laps charged with cerium oxide. Remer's clarity shines in this phase; he explains how to diagnose zone errors, turned-down edges, and surface roughness. He demystifies the act of adjusting the tool shape to bring all four surfaces to a perfect spherical figure. 4. Testing Methodologies

Then came Norman Remer's book. It directly challenged this notion, arguing that making a lens involves the same simple practices and common tools as making a mirror. Once ground, the surfaces are transferred to automated
: A rear, concavo-convex or double-concave lens made of high-dispersion glass (typically Flint SF1) that corrects the color dispersion introduced by the crown lens. It directly challenged this notion, arguing that making

Building a refractor telescope presents several challenges and considerations. These include:
