What materials are generally used to make optical lenses?

We also know that the lens is made of transparent material surface is a spherical part of the optical element, is composed of several pieces of lens, the following for everyone to do a detailed introduction. If you are interested, you can read it.

Optical lens has the characteristics of high transparency, high purity, colorless, uniform texture and good refractive index, which is the main raw material of lens production. In fact, it usually refers to a lens formed by transparent plastic material PMMA (commonly known as acrylic), and it is also made of transparent PC material. Of course, it is important to know that when plastic is used compared to glass, the plastic is susceptible to environmental effects on its optical properties. This is because when the thermal resistance temperature is low and the thermal expansion coefficient is large, the optical element is deformed and the optical characteristics are affected. Optical lenses are less accurate than glass. Due to the relationship between plasticity and material properties, non-uniformity is high, shrinkage deformation is easy to occur, and accuracy is not easy to control. Compared with traditional headlights, lens headlights have uniform brightness and strong penetrability, and have strong penetrability whether in rainy or foggy days. In this way, oncoming vehicles can receive light information at the first time to avoid accidents. It is also 8 to 10 times that of ordinary light bulbs, which can reduce unnecessary troubles caused by changing lights. Optical lens as the main product of our factory, thanks to the strong support of new and old customers, we ensure the reliability of product quality at the same time, let the majority of customers, if you have any technical problems related to the product can also come here at any time to consult.

The optical lens reduces optical performance. A certain amount of output is necessary to achieve economic benefits: plastic injection molding molds are very expensive. At this point, opening a mold can cost hundreds of thousands or millions of dollars. Therefore, if a certain output is not achieved, it is not in line with economic benefits. Generally speaking, the light shape of the lamp after using the lens is the most standard. There can be obvious light and dark cutting lines, and the problem of astigmatism can be solved by focusing. In foreign countries, xenon lamps are used together with standard lenses, so this lens belongs to the category of optical mirrors, which we call "lenses". It has the advantage of small light loss. Professional optical lens companies recommend installing hid headlamps without lenses. For the safety of yourself and others, adding shots is an option. The optical lens had a temperature resistance of 70°C and a heat distortion temperature of 90°C. Therefore, its temperature resistance is poor, suitable for high temperature injection molding. The production efficiency is relatively high. The transmittance of a 3mm thick PMMA lens is about 93%. However, it is relatively fragile after molding and is not suitable for products with complex shapes. If you have something you don't understand, you can call us at any time to consult. You can see the contact information when you enter the official website. You can also consult the online customer service personnel. Will help everyone to solve some problems of quotation method.

After the introduction of the above content, we also have a further understanding of what materials are generally used to make optical lenses. When I see him again in the future, I will not feel strange, and there will be no frequent problems in the process of using it. Well, that's all for today's content. I believe it will bring more wonderful knowledge points.
