A half-ball lens is actually a plane convex lens without an edge. A plane convex lens can focus a collimating beam onto the back focal point or turn a point light source into a collimating beam. Such lenses are used to focus parallel light, or to convert point sources into parallel light. Choose the right material, pay attention to material, bubbles, impurities, uniformity. During grinding, no scratches or indentations are allowed, allowing for interference light.
