Advanced Manufacturing Techniques Of Optical Lens

The manufacture of optical lenses includes the process of cutting the glass slabs with a slitting disk or a glass saw. The pieces are then heated to obtain the desired size and shape. The surfaces are then lapped and ground with the use of diamonds as abrasives. An iron tool is used to grind the surfaces of the lens into flat or curved surfaces.

However, the recently developed optical lens has improved quality compared to the previously manufactured optical lenses. A sophisticated imaging technique is applied to obtain the first 3D high resolution picture. With the use of Optical Coherence Tomography during the process of manufacture, the quality of the lens is considerably improved.

Glass Lenses

The new type of lens includes thousands of layers of plastic which is compressed and bent into the shape of a lens. It gives a precise vision with 3D image resolution. This new technique can be incorporated to improve the manufacturing process of lenses.

Moreover, these lenses are made of plastic which offers an added advantage over glasses. It is light in weight and can be formed into different shapes. Although plastic optics has its own downfalls and challenges, researchers are bent on discovering different techniques to improve the power and quality of the lens.

There are various types of optical lenses which include the simple lens and the compound lenses. If the lens has only one focal point, it is called as simple lens. Lenses which use multiple optical elements are known as compound optical lenses. Most of the corrective lenses are made of concave-convex lenses. These lenses have one concave and one convex side.

Optical Lens

The convex optical lenses are available in different variations. There are lenses with two surfaces known as the biconvex lenses. The biconvex lens is the standard optical lens. Lenses with similar curvature radius are known as equi-convex.

One of the latest developments in the production of optical lens is the green lens. The lenses are created from raw silk from silk worms. The watery solution of silk is poured into a mould and allowed to dry. An organic optical lens is made through this process.
