A Micro Lens Array is a collection of tiny lenses arranged in a grid pattern, typically used to manipulate light in various applications. These arrays can focus, collimate, or disperse light, making them useful in devices like cameras, projectors, and optical sensors. Each lens in the array works independently, allowing for enhanced imaging and light management. Micro Lens Arrays are often made from materials like glass or plastic and can be manufactured using advanced techniques such as photolithography. They play a crucial role in improving the performance of displays, fiber optics, and LED lighting, contributing to better visual experiences and more efficient light usage.
