General introduction:A lens is an optical element made of transparent substances (such as glass, crystal, etc.), which is a device that can aggregate or disperse light, and the resulting images include real images and virtual images. When the lens is imaging, every point on the object All the rays that are emitted to the lens are imaged in the same position, blocking a part of the image, and does not affect the imaging of other rays hitting the lens, so the complete image can still be seen, but due to the reduction of the light hitting the image, So the brightness of the image on the screen will be dimmed.
Product Description:A lens is an optical element made of transparent substances (such as glass, crystal, etc.). The lens is a refractor whose refraction surface is a transparent body with two spherical surfaces (a part of the spherical surface), or a spherical surface (a part of the spherical surface) and a plane. It has both real and virtual images. Lenses can generally be divided into two categories: convex lenses and concave lenses. The central part thicker than the edge part is called a convex lens, and there are three types of biconvex, plano-convex, and concave; Physically, the lens uses the principle of light refraction to form images.
Product category:
1.Convex lens:A convex lens is a lens that is thicker in the center and thinner at the edges. The convex lens has the function of converging light, so it is also called "converging lens", "positive lens" (can be used for hyperopia and reading glasses). Such lenses can be divided into:
a. Double convex lens - is a lens with two convex surfaces;
b. Plano-convex lens - a lens with one side convex and one side flat;
c. Meniscus lens - a lens with a convex side and a concave side.
2.Concave lens:A concave lens is also called a negative spherical lens. The center of the lens is thin and the periphery is thick and concave, so it is also called a concave lens. Concave lenses have a divergent effect on light.
3.Car lens:The light shape of the car lens lens is the most standard, and it can have obvious light and dark cutting lines, which solves the problem of astigmatism through the function of concentrating light.
