Kunshan Noli Optical introduction: What are the functions of optical lenses?
Optical lens is an indispensable component in many optical components. Optical lenses mainly play the role of imaging, focusing, collimating and diffusing light beams. Optical lenses can affect the wavefront curvature of light. An optical lens is a device that can focus or disperse light. The finished image is both a real image and a virtual image.
Applications of optical lenses. Optical lenses are widely used in various high-tech fields, such as security, automobiles, digital cameras, high-power lasers, optical instruments and so on. There are many materials for making optical lenses, such as optically grade glass, PC, PMMA, silicone and so on. We specialize in the production of optical lenses made of optical glass. Lenses of other materials will also be involved in the future.
Optical lenses made of optically grade glass materials. High transparency, high light transmittance, good temperature resistance, long life, uniform texture, good refractive index. There are many kinds of materials that can be used to manufacture optically grade glass lenses, such as fused quartz, calcium fluoride, magnesium fluoride, silicon, germanium, zinc selenide and other materials, as well as a variety of optical colorless glass.
In the production process of optical lenses, various wavelengths of light will be coated by a vacuum coating process. For example, it is usually necessary to coat the lens with an anti-reflection film to reduce the reflection of the lens surface, thereby reducing the loss of light energy, making the image clearer and forming an optical lens with excellent performance. Attention should also be paid to the optical cold processing process of optical lenses.
