Micro Spherical Lens

Micro lenses refer to small lenses with diameters ranging from tens of micrometers to several millimeters. The basic principle is to achieve the focusing or divergence of light by changing the curvature of the lens. When light passes through a microlens, the direction of light propagation can be altered according to the shape of the lens. Microlenses can be divided into two types: convex lenses and concave lenses. Among them, convex lenses can make parallel light converge at the focal point after passing through the lens. When light passes through a convex lens, the center of the lens is thicker and the edge is thinner, causing the light to refract when passing through the lens, thus focusing the light at a single point. On the contrary, concave lenses make parallel light diverge after passing through the lens. The center of a concave lens is thinner and the edge is thicker, causing the light to refract when passing through the lens, thus causing the light to diverge. Due to the extremely small size and unique optical properties of microlenses, they can be used in various fields. They can be made into different shapes and sizes, such as spherical, cylindrical, conical, etc. By combining multiple microlenses together, complex optical systems can be achieved, such as microscopes, telescopes, lasers, etc. The applications of microlenses include optical communication, medical imaging, display technology, optical detection, bioengineering, etc. It is one of the most important technologies in the field of optics at present. With the continuous development and improvement of technology, the application scope of microlens technology will become increasingly wide
