Mikroläätsed

Mikroläätsed, also known as microlenses, are extremely small lenses with diameters typically ranging from a few micrometers to a few millimeters. They are often used in optical systems where miniaturization is crucial. The fabrication of mikroläätsed can involve various techniques, including photolithography, micro-molding, and ion-beam sputtering. Their small size allows them to be integrated into compact devices and complex optical setups.

The optical properties of mikroläätsed, such as focal length and numerical aperture, are determined by their shape, size, and the refractive index of the material they are made from. Common materials include glass, polymers, and semiconductor materials. These lenses can be designed to perform a variety of optical functions, including focusing, collimating, and beam splitting. Their precise manufacturing enables them to achieve high optical performance despite their diminutive scale.

Mikroläätsed find applications in a wide array of fields. They are essential components in digital cameras and mobile phones for image capture. In medical devices, they are used in endoscopes and microscopes for enhanced visualization. Furthermore, they play a role in optical communication systems, laser processing, and in the development of advanced sensors. The continuous development in micro-fabrication technologies is leading to even smaller and more sophisticated mikroläätsed with improved optical characteristics.
