It’s Time you should start your own Plastic Optical Lenses Manufacturing Business

Introduction:

A lens is a transducer that focuses or diverts light or other electromagnetic radiation. A plastic optical lens (PO lens) is a transparent polymer medium used to form images for viewing, either directly, by an eyepiece, or indirectly using a projector. Polymer plastic optical lenses are lighter and more economical than glass lenses. They also have greater resistance to high-energy radiation such as X-rays and gamma rays. Polymerization may be effected in bulk, yielding simple hemispherical lenses known as plano-convex or meniscus elements;

In thin films on a substrate, giving rise to thin meniscus or thick plano-convex elements; or in thin films on molded surfaces, leading to many different shapes having continuously varying curvature from flat to dome shapes. In contrast to optical glasses and crystalline plastics (PMMA), which transmit visible light approximately equally in all directions, polymer lenses concentrate their transmission into a relatively narrow main beam with some spherical aberration. This effect is desirable when imaging concentrated sources such as solar thermal collectors.

Applications:

The plastic optical lenses are used to refract and bend light. The applications include sunglasses, computer screens, microscopes, fiber optics, LEDs and many more. Their essential role is to reduce glare while allowing sufficient light through. They can help cut down on eye strain from bright sunlight and monitor screens by providing a slightly darkened area for reading text. They also increase energy efficiency in lighting by limiting heat transfer when reflected off surfaces or through windows. Further applications are found in camera phone cases and cell phone lens replacements.

 

Business Plan: Manufacturing Business of Plastic Optical Lenses

 

Various scientific uses include high-power microscopy illumination objectives as well as low-power ophthalmic devices such as contact lenses and intraocular lenses that correct vision problems. Most often they form part of pincushion, barrel or doublet magnifiers, including bioptic telescope systems used by people with poor eyesight that magnify images greatly but have other inherent deficiencies. They may be spherical, cylindrical or toroidal sections of varying focal lengths; these shapes minimize aberrations caused by edge diffraction and provide maximum transmission through combination with complementary phase compensating lenses.

Manufacturing Process

Preform and final processing are the two stages of the plastic optical lens manufacturing process. Preforms are made in a variety of shapes and sizes at big plastic extrusion plants. Raw material qualities influence optical quality, whereas technology parameters (flow rate, temperature, barrel length) and processing conditions influence their attributes during subsequent processing (running speed).

Plastic lenses are commonly injection-molded using small to medium injection moulding machines with a two-part clamping system once they have been formed. As a result, incredibly low-cost products are produced. One significant benefit is that optics can be treated immediately after moulding. Polycarbonate is a common optically transparent resin because it has a strong mechanical stability even when exposed to the elements.

Market Demand

Optical Lens Market size worth $ 25,868.81 Million, Globally, by 2028 at 7.33% CAGR. The optical lens market is predicted to grow rapidly in the coming years, owing to the increasing use of convex and concave lenses in the automobile industry. Increasing sales of passenger vehicles, commercial vehicles, and off-road vehicles are driving market expansion, thanks to rising population, rising living standards, rising disposable income, expanding interstate trade, and expanding building and mining operations. The optical lens is widely used in automobile vehicles for mirrors and headlights, paving the way for the optical lens industry. Plastics is a well-known material used to manufacture optical lenses in eyeglasses, sunglasses, etc.

The market for such products is growing rapidly and is expected to be USD 45 billion by. Due to increasing awareness about health hazards associated with long term use of glasses that are made from polycarbonate or other substances, there has been a significant rise in demand for plastic optical lenses which are not only lighter and more affordable but also safer than glass optical lenses. Though their manufacturing costs are higher as compared to those made out of polycarbonate, nevertheless they offer both style and comfort due to their premium nature, high durability and ability to provide wide vision angles.
