The lens is made according to the law of light refraction. It is a refractor and an optical element made of transparent materials (such as glass, crystal, etc.).) The image made of lens includes real image and virtual image, which can be generally divided into two categories: convex lens and concave lens. The center part is thicker than the edge part, which is called convex lens, and there are three kinds of convex, plano-convex and concave-convex. The center part is thinner than the edge part is called concave lens, and there are three kinds of double concave, plano-concave and convex concave. So what is the test standard of lens? Let's introduce it to you.
what is the standard of inspection of the lens:
No bubbles, no dents, no shrinkage marks, no streamline, melting marks within the acceptable range (does not affect the packaging and use function), warping and deformation. The size is within the controllable range (does not affect the assembly or secondary injection molding), the product is wired, and the surface is not bright (does not affect the optical effect)
Lens products through injection molding to obtain qualified products, but also follow the pressure, speed, time, temperature and position of the five elements, as well as some injection rules. But the lens is more stringent than ordinary injection products.
The above content is how the test standard of the lens is introduced. With the continuous development of the market, the lens technology is becoming more and more popular. The lens can be widely used in various fields such as safety, vehicle, digital camera, laser, optical instrument, etc. If the lens is used for a long time and needs to be cleaned regularly, the cleaning and maintenance of the lens can extend the life of the lens.
