When the lens is removed from the generator the back surface is rough, with a frosted appearance, from the process of grinding the prescription onto the blank. This multistep process is called "Fining and polishing". The process involves placing the lenses into a Finer which uses a polishing block called a lap. The first step in the finer ...
Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
Lenses were produced by grinding them against a metal tool called a " lap," which had been produced using a lathe. Convex lenses required a lap having a portion of a hemispherical cavity. A male form was used for concave lenses. The laps could be made from any metal, since hardness was not a major factor.
THE LENSES. When lenses are tilted and turned, their optical power changes. The lens designer must cause the digital lathe to generate curvatures that yield the prescription shown by the test lenses, although the eyewear lenses are tilted and turned. In other words, the lenses "as worn" must give the power "as the patient tested.".
Aspherical lens grinding and polishing, which employs diamond-tipped tools to grind and polish the lens glass; aspherical glass molding, in which the lens glass is pressed and formed using an aspherical mold; aspherical replica technology that uses an aspherical mold to forms aspherical resin on the surface of spherical glass; and aspherical ...

Convex lenses were made by using a concave-shaped grinding tool (and vice-versa), and then the roughly shaped lens was polished to make its final shape. The ordinary glass we use in windows and crockery isn't good enough to use for lenses, because it contains air bubbles and other imperfections.
Define Lapping: The term "lapping" is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.
A lens is a transmissive optical device which focuses or disperses a light beam by means of refraction.A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis.Lenses are made from materials such as glass or plastic, and are ground and polished or molded to a …

For the lens grinding tools I used the bottoms from two other jars. I did not bother grinding the edges of these tools so that they were nice and smooth. I just ground out all the sharp edges. I then proceeded to grind and polish both sides of the lens as if they were a small mirror. For a polishing tool I used the base and stem from an old ...
