Micro-optics, characterized by their small size ranging from a few micrometers to several millimeters, play a crucial role in numerous applications, from microscopy to advanced laser devices. These tiny components, including microlens arrays, microspheres, and micro mirrors, are indispensable in modern technology, performing essential functions such as focusing light and directing light beams.
Types of Micro-Optics
Micro-optics encompass a variety of components, each serving unique purposes in different fields. The primary types include:
- Micro Mirrors: Micro mirrors, small reflective surfaces, are used to steer or fold light beams. They are vital in applications such as miniaturized laser scanning, compact displays, and lightweight medical devices. These mirrors typically feature reflective coatings, either metallic or dielectric multilayer structures. In microscopy, micro mirrors (dichroic mirrors) selectively reflect specific wavelengths while transmitting others.
