Introduction and application of reflector and lens
▲ Reflector 1. Metal reflector: it is generally made of aluminum and needs stamping, polishing, oxidation and other processes. It is easy to form, low cost, high temperature resistance and easy to be recognized by the industry. 2. Plastic reflector: it needs to be demoulded. It has high optical a...Read more -

Installation and cleaning of optical lenses
In the lens installation and cleaning process, any bit of sticky material, even nail marks or oil droplets, will increase the lens absorption rate, reduce the service life. Therefore, the following precautions must be taken: 1. Never install lenses with bare fingers. Glo...Read more -
What’s the difference between optical lenses and Fresnel lenses
Optical lenses are thicker and smaller; Fresnel lenses are thin and large in size. Fresnel lens principle is French physicist Augustine. It was invented by AugustinFresnel, which transformed spherical and aspherical lenses into light and thin planar shape lenses to achie...Read more -
The processing process of optical lens is introduced
Optical cold working 1. Polish the optical lens, the purpose is to erase some rough substances on the surface of the optical lens, so that the optical lens has a preliminary model. 2. After the initial polishing, poli...Read more
