mikropeilejä

Mikropeilejä are small, typically metal-coated glass or plastic components used in optical systems. Their primary function is to redirect light with a high degree of precision. These components are often square or rectangular and can vary significantly in size, with some measuring only a few millimeters across, hence the term "mikro" (micro).

The reflective surface of a mikropeili is crucial. It's usually created by depositing a thin layer of a reflective material, such as aluminum or silver, onto a substrate. The quality of this coating directly impacts the mirror's performance, including its reflectivity and durability. Mikropeilejä are designed to withstand specific environmental conditions and optical requirements.

These miniature mirrors find applications in a wide range of technologies. They are commonly employed in barcode scanners, where they help direct laser beams to read product codes. In consumer electronics, they can be found in digital cameras and projectors for image manipulation and light path folding. Industrial automation and scientific instrumentation also utilize mikropeilejä for precise alignment and beam steering in complex optical setups. The development of microelectromechanical systems (MEMS) has further expanded their use, enabling the creation of sophisticated optical devices with integrated micro-mirrors that can be electrically controlled to adjust their angle.
