Optical manufacturing and testing - Wikipedia

31/03/2006  Optical manufacturing and testing spans an enormous range of manufacturing procedures and optical test configurations.. The manufacture of a conventional spherical lens typically begins with the generation of the optic's rough shape by grinding a glass blank. This can be done, for example, with ring tools. Next, the lens surface is polished to its final form.

THE CHALLENGE OF GRINDING LENSES FOR SINGLE

Anyone who has ever read about lens grinding techniques is aware that the main resource for succeeding is the grinding powders. These are a series of abrasive powders that have to be employed, firstly to generate the curvatures and then for making them smoother to an almost polished finish. The grade may vary from grit 80 up to grit 2000. Generally they are made of carborundum (silicon carbide ...

An Introduction to the Optics Manufacturing Process

31/10/2008  Blocking and Grinding Before the lens undergoes further grinding, the lens must be blocked, or mounted, to begin the process. Blocking involves mounting lenses onto a convex or concave surface (inverse of the tool being used) with pitch or wax. A lens can be blocked individually (Figure 3a), but more often, many lenses with the same radii are mounted on one surface for high production

Slab-off, Reverse Slab-off and Bi-centric Grinding

This produces a unique optical axis for each of the two portions of the lens. Bi-centric grinding can be done on either the front surface in the case of a fused lens such as a glass flat top bifocal, or on the back surface in the case of a lens where the multi-focal segment results in a wedge on the front surface such as a plastic bifocal. Reverse slab-off lenses are molded, or cast, with base ...

From there, the lens goes through generation where the rough shape is ground into the blank. A lens is then blocked and undergoes further grinding to improve the surface and shape. Polishing is the final fine grinding stage

Tiny lenses Lens on Leeuwenhoek

Grinding is the traditional way to make a small lens. In Leeuwenhoek's time, glass grinding techniques were based on the centuries-old technique of grinding lenses for eye-glasses (spectacles). Grind a piece of glass under a cap or mold coated with increasingly fine material. Then polish it. The tiny cap containing the material, the grinding sand or the polishing paste, fits over the glass.
