Product Details
The center is thicker than the edge and has a converging effect on the light, so it is also called a converging lens. According to different shapes, convex lenses can be divided into biconvex lenses, plano-convex lenses and meniscus lenses, etc., by refracting light to change its propagation direction, so as to achieve the effect of image magnification, reduction, handstand or upright. The special shape leads to its unique optical properties. When the light passes through the cylindrical mirror, the light will be focused into a straight line or other forms of deformation. This property gives cylindrical lenses significant advantages in changing the size of the image, such as converting a point spot into a line spot, or changing the height of the image without changing the image width.
